One problem I ran into many times in the past is that, with this kind of code:

my $s = IO::Socket::INET->new(Proto => "tcp", LocalAddr => "localhost"
+, LocalPort => 3000, Listen => 10);

for (my $c = $s->accept()) {
      ...
}

If you leave it alone for hours and there is no client come to connect, you might never be able to accept() connection any more, even when there is client wants to conenct. I ran into this many times in the past. To resolve this, I simply let the accept() timeout periodically.

"But why would accept in one pseudo-process (thread) tie up a function (fork) in another pseudo-process (thread)? "

Don't jump to conclusion that this has anything to do with thread, unless you come up a piece of threading code to demo the same problem.
