| - setuid/setgid must effect process | 
 |   + test syscalls (getuid) afterwards | 
 |   + test core file content | 
 |  | 
 |   + use UID/GID in access(2), chmod(2), chown(2), link(2) | 
 |  | 
 | - nice level is process property | 
 |  | 
 | - rlimit should be process-wide and SIGXCPU should be sent if all threads | 
 |   together exceed the limit | 
 |  | 
 | - getrusage() must return resource utilization for the process | 
 |  | 
 |  |

 | The following are possible optimizations and in no way required: | 
 |  | 
 |  | 
 | - the scheduler should be thread group-aware, i.e., it has to give time to | 
 |   the thread group not proportional to the number of threads. |
