Just a theory, but the normal rule when a process forks, is that both children inherit all open file handles, including sockets, so if your parent process forks while it holds a socket connection to your child, then your child will block if either side of that fork fails to close the socket.

In addition, you say that you are seeing strange behaviour on windows. I to have seen perl under windows do all kinds of strange things with sockets in the past, to the extent that I would now not trust windows to have a reliable implementation.
