+vda: here is why:

+In libpthread/linuxthreads.old/sysdeps/pthread/bits/libc-lock.h
+adding libc_hidden_proto(foo) just before weak_extern (__pthread_initialize)
+will not warn:
+ /* libc_hidden_proto(foo) */
+ weak_extern (__pthread_initialize)
+ /* libc_hidden_proto(foo) */
+but adding after will! Which is extremely strange -
+weak_extern expands into just "#pragma weak __pthread_initialize".
+TODO: determine whether it is a gcc bug or what
+(see gcc.gnu.org/PR36282).
+For now, just include all headers before internals.h

+This chapter describes the pthreads (POSIX threads) library. This

+primitives, synchronization objects, and so forth. It also implements
+POSIX 1003.1b semaphores (not to be confused with System V semaphores).
+
+The threads operations (@samp{pthread_*}) do not use @var{errno}.
+Instead they return an error code directly. The semaphore operations do
+use @var{errno}.

+@comment POSIX
+@deftypefun int pthread_create (pthread_t * @var{thread}, pthread_attr_t * @var{attr}, void * (*@var{start_routine})(void *), void * @var{arg})
+@code{pthread_create} creates a new thread of control that executes
+concurrently with the calling thread. The new thread calls the
+function @var{start_routine}, passing it @var{arg} as first argument. The
+new thread terminates either explicitly, by calling @code{pthread_exit},
+or implicitly, by returning from the @var{start_routine} function. The
+latter case is equivalent to calling @code{pthread_exit} with the result
+returned by @var{start_routine} as exit code.
+
+The @var{attr} argument specifies thread attributes to be applied to the
+new thread. @xref{Thread Attributes}, for details. The @var{attr}
+argument can also be @code{NULL}, in which case default attributes are
+used: the created thread is joinable (not detached) and has an ordinary
+(not realtime) scheduling policy.
+
+On success, the identifier of the newly created thread is stored in the
+location pointed by the @var{thread} argument, and a 0 is returned. On
+error, a non-zero error code is returned.
+
+This function may return the following errors:
+@table @code
+@item EAGAIN
+Not enough system resources to create a process for the new thread,
+or more than @code{PTHREAD_THREADS_MAX} threads are already active.
+@end table
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun void pthread_exit (void *@var{retval})
+@code{pthread_exit} terminates the execution of the calling thread. All
+cleanup handlers (@pxref{Cleanup Handlers}) that have been set for the
+calling thread with @code{pthread_cleanup_push} are executed in reverse
+order (the most recently pushed handler is executed first). Finalization
+functions for thread-specific data are then called for all keys that
+have non-@code{NULL} values associated with them in the calling thread
+(@pxref{Thread-Specific Data}). Finally, execution of the calling
+thread is stopped.
+
+The @var{retval} argument is the return value of the thread. It can be
+retrieved from another thread using @code{pthread_join}.
+
+The @code{pthread_exit} function never returns.
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_cancel (pthread_t @var{thread})
+
+@code{pthread_cancel} sends a cancellation request to the thread denoted
+by the @var{thread} argument. If there is no such thread,
+@code{pthread_cancel} fails and returns @code{ESRCH}. Otherwise it
+returns 0. @xref{Cancellation}, for details.
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_join (pthread_t @var{th}, void **thread_@var{return})
+@code{pthread_join} suspends the execution of the calling thread until
+the thread identified by @var{th} terminates, either by calling
+@code{pthread_exit} or by being canceled.
+
+If @var{thread_return} is not @code{NULL}, the return value of @var{th}
+is stored in the location pointed to by @var{thread_return}. The return
+value of @var{th} is either the argument it gave to @code{pthread_exit},
+or @code{PTHREAD_CANCELED} if @var{th} was canceled.
+
+The joined thread @code{th} must be in the joinable state: it must not
+have been detached using @code{pthread_detach} or the
+@code{PTHREAD_CREATE_DETACHED} attribute to @code{pthread_create}.
+
+When a joinable thread terminates, its memory resources (thread
+descriptor and stack) are not deallocated until another thread performs
+@code{pthread_join} on it. Therefore, @code{pthread_join} must be called
+once for each joinable thread created to avoid memory leaks.
+
+At most one thread can wait for the termination of a given
+thread. Calling @code{pthread_join} on a thread @var{th} on which
+another thread is already waiting for termination returns an error.
+
+@code{pthread_join} is a cancellation point. If a thread is canceled
+while suspended in @code{pthread_join}, the thread execution resumes
+immediately and the cancellation is executed without waiting for the
+@var{th} thread to terminate. If cancellation occurs during
+@code{pthread_join}, the @var{th} thread remains not joined.
+
+On success, the return value of @var{th} is stored in the location
+pointed to by @var{thread_return}, and 0 is returned. On error, one of
+the following values is returned:
+@table @code
+@item ESRCH
+No thread could be found corresponding to that specified by @var{th}.
+@item EINVAL
+The @var{th} thread has been detached, or another thread is already
+waiting on termination of @var{th}.
+@item EDEADLK
+The @var{th} argument refers to the calling thread.

+@node Thread Attributes
+@section Thread Attributes
+
+@comment pthread.h
+@comment POSIX
+
+Threads have a number of attributes that may be set at creation time.
+This is done by filling a thread attribute object @var{attr} of type
+@code{pthread_attr_t}, then passing it as second argument to
+@code{pthread_create}. Passing @code{NULL} is equivalent to passing a
+thread attribute object with all attributes set to their default values.
+
+Attribute objects are consulted only when creating a new thread. The
+same attribute object can be used for creating several threads.
+Modifying an attribute object after a call to @code{pthread_create} does
+not change the attributes of the thread previously created.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_attr_init (pthread_attr_t *@var{attr})
+@code{pthread_attr_init} initializes the thread attribute object
+@var{attr} and fills it with default values for the attributes. (The
+default values are listed below for each attribute.)
+
+Each attribute @var{attrname} (see below for a list of all attributes)
+can be individually set using the function
+@code{pthread_attr_set@var{attrname}} and retrieved using the function
+@code{pthread_attr_get@var{attrname}}.
+@end deftypefun
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_attr_destroy (pthread_attr_t *@var{attr})
+@code{pthread_attr_destroy} destroys the attribute object pointed to by
+@var{attr} releasing any resources associated with it. @var{attr} is
+left in an undefined state, and you must not use it again in a call to
+any pthreads function until it has been reinitialized.

+values they can take.
+

+
+These functions always return 0.
+@end deftypefun
+
+The following thread attributes are supported:
+@table @samp
+@item detachstate
+Choose whether the thread is created in the joinable state (value
+@code{PTHREAD_CREATE_JOINABLE}) or in the detached state
+(@code{PTHREAD_CREATE_DETACHED}). The default is
+@code{PTHREAD_CREATE_JOINABLE}.
+
+In the joinable state, another thread can synchronize on the thread
+termination and recover its termination code using @code{pthread_join},
+but some of the thread resources are kept allocated after the thread
+terminates, and reclaimed only when another thread performs
+@code{pthread_join} on that thread.
+
+In the detached state, the thread resources are immediately freed when
+it terminates, but @code{pthread_join} cannot be used to synchronize on
+the thread termination.
+
+A thread created in the joinable state can later be put in the detached
+thread using @code{pthread_detach}.
+
+@item schedpolicy
+Select the scheduling policy for the thread: one of @code{SCHED_OTHER}
+(regular, non-realtime scheduling), @code{SCHED_RR} (realtime,
+round-robin) or @code{SCHED_FIFO} (realtime, first-in first-out).
+The default is @code{SCHED_OTHER}.
+@c Not doc'd in our manual: FIXME.
+@c See @code{sched_setpolicy} for more information on scheduling policies.
+
+The realtime scheduling policies @code{SCHED_RR} and @code{SCHED_FIFO}
+are available only to processes with superuser privileges.
+@code{pthread_attr_setschedparam} will fail and return @code{ENOTSUP} if
+you try to set a realtime policy when you are unprivileged.
+
+The scheduling policy of a thread can be changed after creation with
+@code{pthread_setschedparam}.
+
+@item schedparam
+Change the scheduling parameter (the scheduling priority)
+for the thread. The default is 0.
+
+This attribute is not significant if the scheduling policy is
+@code{SCHED_OTHER}; it only matters for the realtime policies
+@code{SCHED_RR} and @code{SCHED_FIFO}.
+
+The scheduling priority of a thread can be changed after creation with
+@code{pthread_setschedparam}.
+
+@item inheritsched
+Choose whether the scheduling policy and scheduling parameter for the
+newly created thread are determined by the values of the
+@var{schedpolicy} and @var{schedparam} attributes (value
+@code{PTHREAD_EXPLICIT_SCHED}) or are inherited from the parent thread
+(value @code{PTHREAD_INHERIT_SCHED}). The default is
+@code{PTHREAD_EXPLICIT_SCHED}.
+
+@item scope
+Choose the scheduling contention scope for the created thread. The
+default is @code{PTHREAD_SCOPE_SYSTEM}, meaning that the threads contend
+for CPU time with all processes running on the machine. In particular,
+thread priorities are interpreted relative to the priorities of all
+other processes on the machine. The other possibility,
+@code{PTHREAD_SCOPE_PROCESS}, means that scheduling contention occurs
+only between the threads of the running process: thread priorities are
+interpreted relative to the priorities of the other threads of the
+process, regardless of the priorities of other processes.
+
+@code{PTHREAD_SCOPE_PROCESS} is not supported in LinuxThreads. If you
+try to set the scope to this value, @code{pthread_attr_setscope} will
+fail and return @code{ENOTSUP}.
+
+@item stackaddr
+Provide an address for an application managed stack. The size of the
+stack must be at least @code{PTHREAD_STACK_MIN}.
+
+@item stacksize
+Change the size of the stack created for the thread. The value defines
+the minimum stack size, in bytes.
+
+If the value exceeds the system's maximum stack size, or is smaller
+than @code{PTHREAD_STACK_MIN}, @code{pthread_attr_setstacksize} will
+fail and return @code{EINVAL}.
+
+@item stack
+Provide both the address and size of an application managed stack to
+use for the new thread. The base of the memory area is @var{stackaddr}
+with the size of the memory area, @var{stacksize}, measured in bytes.
+
+If the value of @var{stacksize} is less than @code{PTHREAD_STACK_MIN},
+or greater than the system's maximum stack size, or if the value of
+@var{stackaddr} lacks the proper alignment, @code{pthread_attr_setstack}
+will fail and return @code{EINVAL}.
+
+@item guardsize
+Change the minimum size in bytes of the guard area for the thread's
+stack. The default size is a single page. If this value is set, it
+will be rounded up to the nearest page size. If the value is set to 0,
+a guard area will not be created for this thread. The space allocated
+for the guard area is used to catch stack overflow. Therefore, when
+allocating large structures on the stack, a larger guard area may be
+required to catch a stack overflow.
+
+If the caller is managing their own stacks (if the @code{stackaddr}
+attribute has been set), then the @code{guardsize} attribute is ignored.
+
+If the value exceeds the @code{stacksize}, @code{pthread_atrr_setguardsize}
+will fail and return @code{EINVAL}.
+@end table
+
+@node Cancellation
+@section Cancellation
+
+Cancellation is the mechanism by which a thread can terminate the
+execution of another thread. More precisely, a thread can send a
+cancellation request to another thread. Depending on its settings, the
+target thread can then either ignore the request, honor it immediately,
+or defer it till it reaches a cancellation point. When threads are
+first created by @code{pthread_create}, they always defer cancellation
+requests.
+
+When a thread eventually honors a cancellation request, it behaves as if
+@code{pthread_exit(PTHREAD_CANCELED)} was called. All cleanup handlers
+are executed in reverse order, finalization functions for
+thread-specific data are called, and finally the thread stops executing.
+If the canceled thread was joinable, the return value
+@code{PTHREAD_CANCELED} is provided to whichever thread calls
+@var{pthread_join} on it. See @code{pthread_exit} for more information.
+
+Cancellation points are the points where the thread checks for pending
+cancellation requests and performs them. The POSIX threads functions
+@code{pthread_join}, @code{pthread_cond_wait},
+@code{pthread_cond_timedwait}, @code{pthread_testcancel},
+@code{sem_wait}, and @code{sigwait} are cancellation points. In
+addition, these system calls are cancellation points:
+
+@multitable @columnfractions .33 .33 .33
+@item @t{accept} @tab @t{open} @tab @t{sendmsg}
+@item @t{close} @tab @t{pause} @tab @t{sendto}

+@item @t{msync} @tab @t{send} @tab @t{write}
+@item @t{nanosleep}
+@end multitable
+
+@noindent
+All library functions that call these functions (such as
+@code{printf}) are also cancellation points.

+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_setcancelstate (int @var{state}, int *@var{oldstate})
+@code{pthread_setcancelstate} changes the cancellation state for the

+not. The @var{state} argument is the new cancellation state: either
+@code{PTHREAD_CANCEL_ENABLE} to enable cancellation, or
+@code{PTHREAD_CANCEL_DISABLE} to disable cancellation (cancellation
+requests are ignored).
+

+
+If the @var{state} argument is not @code{PTHREAD_CANCEL_ENABLE} or

+@deftypefun int pthread_setcanceltype (int @var{type}, int *@var{oldtype})
+@code{pthread_setcanceltype} changes the type of responses to

+or deferred. The @var{type} argument is the new cancellation type:
+either @code{PTHREAD_CANCEL_ASYNCHRONOUS} to cancel the calling thread
+as soon as the cancellation request is received, or
+@code{PTHREAD_CANCEL_DEFERRED} to keep the cancellation request pending
+until the next cancellation point. If @var{oldtype} is not @code{NULL},
+the previous cancellation state is stored in the location pointed to by
+@var{oldtype}, and can thus be restored later by another call to
+@code{pthread_setcanceltype}.
+
+If the @var{type} argument is not @code{PTHREAD_CANCEL_DEFERRED} or
+@code{PTHREAD_CANCEL_ASYNCHRONOUS}, @code{pthread_setcanceltype} fails

+@deftypefun void pthread_testcancel (@var{void})

+cancellation point functions otherwise.
+@end deftypefun
+
+@node Cleanup Handlers
+@section Cleanup Handlers
+
+Cleanup handlers are functions that get called when a thread terminates,
+either by calling @code{pthread_exit} or because of
+cancellation. Cleanup handlers are installed and removed following a
+stack-like discipline.
+
+The purpose of cleanup handlers is to free the resources that a thread
+may hold at the time it terminates. In particular, if a thread exits or
+is canceled while it owns a locked mutex, the mutex will remain locked
+forever and prevent other threads from executing normally. The best way
+to avoid this is, just before locking the mutex, to install a cleanup
+handler whose effect is to unlock the mutex. Cleanup handlers can be
+used similarly to free blocks allocated with @code{malloc} or close file
+descriptors on thread termination.
+
+Here is how to lock a mutex @var{mut} in such a way that it will be
+unlocked if the thread is canceled while @var{mut} is locked:
+
+@smallexample
+pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
+pthread_mutex_lock(&mut);
+/* do some work */
+pthread_mutex_unlock(&mut);
+pthread_cleanup_pop(0);
+@end smallexample
+
+Equivalently, the last two lines can be replaced by
+
+@smallexample
+pthread_cleanup_pop(1);
+@end smallexample
+
+Notice that the code above is safe only in deferred cancellation mode
+(see @code{pthread_setcanceltype}). In asynchronous cancellation mode, a
+cancellation can occur between @code{pthread_cleanup_push} and
+@code{pthread_mutex_lock}, or between @code{pthread_mutex_unlock} and
+@code{pthread_cleanup_pop}, resulting in both cases in the thread trying
+to unlock a mutex not locked by the current thread. This is the main
+reason why asynchronous cancellation is difficult to use.
+
+If the code above must also work in asynchronous cancellation mode,
+then it must switch to deferred mode for locking and unlocking the
+mutex:
+
+@smallexample
+pthread_setcanceltype(PTHREAD_CANCEL_DEFERRED, &oldtype);
+pthread_cleanup_push(pthread_mutex_unlock, (void *) &mut);
+pthread_mutex_lock(&mut);
+/* do some work */
+pthread_cleanup_pop(1);
+pthread_setcanceltype(oldtype, NULL);
+@end smallexample
+
+The code above can be rewritten in a more compact and efficient way,
+using the non-portable functions @code{pthread_cleanup_push_defer_np}
+and @code{pthread_cleanup_pop_restore_np}:
+
+@smallexample
+pthread_cleanup_push_defer_np(pthread_mutex_unlock, (void *) &mut);
+pthread_mutex_lock(&mut);

+@node Mutexes
+@section Mutexes
+
+A mutex is a MUTual EXclusion device, and is useful for protecting
+shared data structures from concurrent modifications, and implementing
+critical sections and monitors.
+
+A mutex has two possible states: unlocked (not owned by any thread),
+and locked (owned by one thread). A mutex can never be owned by two
+different threads simultaneously. A thread attempting to lock a mutex
+that is already locked by another thread is suspended until the owning
+thread unlocks the mutex first.
+
+None of the mutex functions is a cancellation point, not even
+@code{pthread_mutex_lock}, in spite of the fact that it can suspend a
+thread for arbitrary durations. This way, the status of mutexes at
+cancellation points is predictable, allowing cancellation handlers to
+unlock precisely those mutexes that need to be unlocked before the
+thread stops executing. Consequently, threads using deferred
+cancellation should never hold a mutex for extended periods of time.
+
+It is not safe to call mutex functions from a signal handler. In
+particular, calling @code{pthread_mutex_lock} or
+@code{pthread_mutex_unlock} from a signal handler may deadlock the
+calling thread.

+@section Thread-Specific Data
+
+Programs often need global or static variables that have different
+values in different threads. Since threads share one memory space, this
+cannot be achieved with regular variables. Thread-specific data is the
+POSIX threads answer to this need.
+
+Each thread possesses a private memory block, the thread-specific data
+area, or TSD area for short. This area is indexed by TSD keys. The TSD
+area associates values of type @code{void *} to TSD keys. TSD keys are
+common to all threads, but the value associated with a given TSD key can
+be different in each thread.
+
+For concreteness, the TSD areas can be viewed as arrays of @code{void *}
+pointers, TSD keys as integer indices into these arrays, and the value
+of a TSD key as the value of the corresponding array element in the
+calling thread.
+
+When a thread is created, its TSD area initially associates @code{NULL}
+with all keys.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_key_create (pthread_key_t *@var{key}, void (*destr_function) (void *))
+@code{pthread_key_create} allocates a new TSD key. The key is stored in
+the location pointed to by @var{key}. There is a limit of
+@code{PTHREAD_KEYS_MAX} on the number of keys allocated at a given
+time. The value initially associated with the returned key is
+@code{NULL} in all currently executing threads.
+
+The @var{destr_function} argument, if not @code{NULL}, specifies a
+destructor function associated with the key. When a thread terminates
+via @code{pthread_exit} or by cancellation, @var{destr_function} is
+called on the value associated with the key in that thread. The
+@var{destr_function} is not called if a key is deleted with
+@code{pthread_key_delete} or a value is changed with
+@code{pthread_setspecific}. The order in which destructor functions are
+called at thread termination time is unspecified.
+
+Before the destructor function is called, the @code{NULL} value is
+associated with the key in the current thread. A destructor function
+might, however, re-associate non-@code{NULL} values to that key or some
+other key. To deal with this, if after all the destructors have been
+called for all non-@code{NULL} values, there are still some
+non-@code{NULL} values with associated destructors, then the process is
+repeated. The LinuxThreads implementation stops the process after
+@code{PTHREAD_DESTRUCTOR_ITERATIONS} iterations, even if some
+non-@code{NULL} values with associated descriptors remain. Other
+implementations may loop indefinitely.
+
+@code{pthread_key_create} returns 0 unless @code{PTHREAD_KEYS_MAX} keys
+have already been allocated, in which case it fails and returns

+returns. The signals in @var{set} must be blocked and not ignored on
+entrance to @code{sigwait}. If the delivered signal has a signal handler
+function attached, that function is @emph{not} called.
+
+@code{sigwait} is a cancellation point. It always returns 0.
+@end deftypefun
+
+For @code{sigwait} to work reliably, the signals being waited for must be
+blocked in all threads, not only in the calling thread, since
+otherwise the POSIX semantics for signal delivery do not guarantee
+that it's the thread doing the @code{sigwait} that will receive the signal.
+The best way to achieve this is block those signals before any threads
+are created, and never unblock them in the program other than by
+calling @code{sigwait}.
+
+Signal handling in LinuxThreads departs significantly from the POSIX
+standard. According to the standard, ``asynchronous'' (external) signals
+are addressed to the whole process (the collection of all threads),
+which then delivers them to one particular thread. The thread that
+actually receives the signal is any thread that does not currently block
+the signal.
+
+In LinuxThreads, each thread is actually a kernel process with its own
+PID, so external signals are always directed to one particular thread.
+If, for instance, another thread is blocked in @code{sigwait} on that
+signal, it will not be restarted.
+
+The LinuxThreads implementation of @code{sigwait} installs dummy signal
+handlers for the signals in @var{set} for the duration of the
+wait. Since signal handlers are shared between all threads, other
+threads must not attach their own signal handlers to these signals, or
+alternatively they should all block these signals (which is recommended
+anyway).
+
+@node Threads and Fork
+@section Threads and Fork
+
+It's not intuitively obvious what should happen when a multi-threaded POSIX
+process calls @code{fork}. Not only are the semantics tricky, but you may
+need to write code that does the right thing at fork time even if that code
+doesn't use the @code{fork} function. Moreover, you need to be aware of
+interaction between @code{fork} and some library features like
+@code{pthread_once} and stdio streams.
+
+When @code{fork} is called by one of the threads of a process, it creates a new
+process which is copy of the calling process. Effectively, in addition to
+copying certain system objects, the function takes a snapshot of the memory
+areas of the parent process, and creates identical areas in the child.
+To make matters more complicated, with threads it's possible for two or more
+threads to concurrently call fork to create two or more child processes.
+
+The child process has a copy of the address space of the parent, but it does
+not inherit any of its threads. Execution of the child process is carried out
+by a new thread which returns from @code{fork} function with a return value of
+zero; it is the only thread in the child process. Because threads are not
+inherited across fork, issues arise. At the time of the call to @code{fork},
+threads in the parent process other than the one calling @code{fork} may have
+been executing critical regions of code. As a result, the child process may
+get a copy of objects that are not in a well-defined state. This potential
+problem affects all components of the program.
+
+Any program component which will continue being used in a child process must
+correctly handle its state during @code{fork}. For this purpose, the POSIX
+interface provides the special function @code{pthread_atfork} for installing
+pointers to handler functions which are called from within @code{fork}.
+
+@comment pthread.h
+@comment POSIX
+@deftypefun int pthread_atfork (void (*@var{prepare})(void), void (*@var{parent})(void), void (*@var{child})(void))
+
+@code{pthread_atfork} registers handler functions to be called just
+before and just after a new process is created with @code{fork}. The
+@var{prepare} handler will be called from the parent process, just
+before the new process is created. The @var{parent} handler will be
+called from the parent process, just before @code{fork} returns. The
+@var{child} handler will be called from the child process, just before
+@code{fork} returns.
+
+@code{pthread_atfork} returns 0 on success and a non-zero error code on
+error.
+
+One or more of the three handlers @var{prepare}, @var{parent} and
+@var{child} can be given as @code{NULL}, meaning that no handler needs
+to be called at the corresponding point.
+
+@code{pthread_atfork} can be called several times to install several
+sets of handlers. At @code{fork} time, the @var{prepare} handlers are
+called in LIFO order (last added with @code{pthread_atfork}, first
+called before @code{fork}), while the @var{parent} and @var{child}
+handlers are called in FIFO order (first added, first called).
+
+If there is insufficient memory available to register the handlers,
+@code{pthread_atfork} fails and returns @code{ENOMEM}. Otherwise it
+returns 0.
+
+The functions @code{fork} and @code{pthread_atfork} must not be regarded as
+reentrant from the context of the handlers. That is to say, if a
+@code{pthread_atfork} handler invoked from within @code{fork} calls
+@code{pthread_atfork} or @code{fork}, the behavior is undefined.
+
+Registering a triplet of handlers is an atomic operation with respect to fork.
+If new handlers are registered at about the same time as a fork occurs, either
+all three handlers will be called, or none of them will be called.
+
+The handlers are inherited by the child process, and there is no
+way to remove them, short of using @code{exec} to load a new
+pocess image.
+
+@end deftypefun
+
+To understand the purpose of @code{pthread_atfork}, recall that
+@code{fork} duplicates the whole memory space, including mutexes in
+their current locking state, but only the calling thread: other threads
+are not running in the child process. The mutexes are not usable after
+the @code{fork} and must be initialized with @code{pthread_mutex_init}
+in the child process. This is a limitation of the current
+implementation and might or might not be present in future versions.
+
+To avoid this, install handlers with @code{pthread_atfork} as follows: have the
+@var{prepare} handler lock the mutexes (in locking order), and the
+@var{parent} handler unlock the mutexes. The @var{child} handler should reset
+the mutexes using @code{pthread_mutex_init}, as well as any other
+synchronization objects such as condition variables.
+
+Locking the global mutexes before the fork ensures that all other threads are
+locked out of the critical regions of code protected by those mutexes. Thus
+when @code{fork} takes a snapshot of the parent's address space, that snapshot
+will copy valid, stable data. Resetting the synchronization objects in the
+child process will ensure they are properly cleansed of any artifacts from the
+threading subsystem of the parent process. For example, a mutex may inherit
+a wait queue of threads waiting for the lock; this wait queue makes no sense
+in the child process. Initializing the mutex takes care of this.
+
+@node Streams and Fork
+@section Streams and Fork
+
+The GNU standard I/O library has an internal mutex which guards the internal
+linked list of all standard C FILE objects. This mutex is properly taken care
+of during @code{fork} so that the child receives an intact copy of the list.
+This allows the @code{fopen} function, and related stream-creating functions,
+to work correctly in the child process, since these functions need to insert
+into the list.
+
+However, the individual stream locks are not completely taken care of. Thus
+unless the multithreaded application takes special precautions in its use of
+@code{fork}, the child process might not be able to safely use the streams that
+it inherited from the parent. In general, for any given open stream in the
+parent that is to be used by the child process, the application must ensure
+that that stream is not in use by another thread when @code{fork} is called.
+Otherwise an inconsistent copy of the stream object be produced. An easy way to
+ensure this is to use @code{flockfile} to lock the stream prior to calling
+@code{fork} and then unlock it with @code{funlockfile} inside the parent
+process, provided that the parent's threads properly honor these locks.
+Nothing special needs to be done in the child process, since the library
+internally resets all stream locks.
+
+Note that the stream locks are not shared between the parent and child.
+For example, even if you ensure that, say, the stream @code{stdout} is properly
+treated and can be safely used in the child, the stream locks do not provide
+an exclusion mechanism between the parent and child. If both processes write
+to @code{stdout}, strangely interleaved output may result regardless of
+the explicit use of @code{flockfile} or implicit locks.
+
+Also note that these provisions are a GNU extension; other systems might not
+provide any way for streams to be used in the child of a multithreaded process.
+POSIX requires that such a child process confines itself to calling only
+asynchronous safe functions, which excludes much of the library, including
+standard I/O.

+@deftypefun void pthread_kill_other_threads_np (@var{void})
+@code{pthread_kill_other_threads_np} is a non-portable LinuxThreads extension.
+It causes all threads in the program to terminate immediately, except
+the calling thread which proceeds normally. It is intended to be
+called just before a thread calls one of the @code{exec} functions,
+e.g. @code{execve}.
+
+Termination of the other threads is not performed through
+@code{pthread_cancel} and completely bypasses the cancellation
+mechanism. Hence, the current settings for cancellation state and
+cancellation type are ignored, and the cleanup handlers are not
+executed in the terminated threads.
+
+According to POSIX 1003.1c, a successful @code{exec*} in one of the
+threads should automatically terminate all other threads in the program.
+This behavior is not yet implemented in LinuxThreads. Calling

+argument points to a static or extern variable statically initialized
+to @code{PTHREAD_ONCE_INIT}.
+
+The first time @code{pthread_once} is called with a given
+@var{once_control} argument, it calls @var{init_routine} with no

+@code{pthread_once} with the same @code{once_control} argument do
+nothing.
+
+If a thread is cancelled while executing @var{init_routine}
+the state of the @var{once_control} variable is reset so that

+
+If the process forks while one or more threads are executing
