I’m not so sure about that. I’ve done a bunch of development on a system recently which had a server process written in Python running on a Linux box, accepting connections from a client running under old MacOS 9 (don’t ask) which was, of course, prone to crash. If the client had shut down cleanly, then I could stop and restart the server process without any problems reopening the socket. But if I forgot to close the client, then the server would hit the “already in use” error. To deal with it, I simply put in an automatic retry at 60-second intervals until it succeeded in reopening the socket. -- http://mail.python.org/mailman/listinfo/python-list
