I still get a few delays of a minute or two, and sometimes I don't, but
that is about the maximum. I'm running RedHat 5.1. Perhaps that's
because I always manage to get the shutdown and close in properly.
This is it, literally:
static void
killSocket(int s)
{
TRACE("killSocket", s);
shutdown(s, 2);
#if defined(_WIN32)
closesocket(s);
#elif defined(AMIGA)
CloseSocket(s);
#else
close(s);
#endif
}
One thing you could try (I thought I had it in!) is to use setsockopt
with SO_REUSEADDR.

Don't design inefficiency in - it'll happen in the implementation. - me
