+---
+Happy Eyeballs is an algorithm that attempts to connect to both IPv4 and IPv6
+addresses for dual-stack hosts, giving IPv6 a head-start of the specified
+number of milliseconds. If the IPv6 address cannot be connected to within that
+time, then a connection attempt is made to the IPv4 address in parallel. The
+first connection to be established is the one that is used.
+
+The range of suggested useful values is limited. Happy Eyeballs RFC 6555 says
+"It is RECOMMENDED that connection attempts be paced 150-250 ms apart to
+balance human factors against network load." libcurl currently defaults to
+200 ms. Firefox and Chrome currently default to 300 ms.
