[Freeciv-Dev] [PATCH] make accepting new connects nonblocking

[Markus Linnala <maage@xxxxxxxxx>]

I've run freeciv with profiler.

There seems to be some kind of problem with connecting clients.
Sometimes I have to connect and disconnect several times before
games starts to run.

This patch fixes the problem, but I'm not sure it fixes problem
at freeciv or at glibc / socket implementation.

My system is linux 2.2.14, RH6.1, glibc 2.1.2.
