Unless some extraneous error condition occurs, or some type of timeout.

Specifically invalid data (munched packet) recieved on a socket can
invoke this condition.

Have you considered just using something like libevent to manage the
socket communications? http://www.monkey.org/~provos/libevent/  Writing
a socket listener is easy, writing a really robust socket listner is
hard.
