Message 119824 - Python tracker

I would need opinions on one more thing. The current patch warns when a socket has not been explicitly closed. But it does so even when the socket isn't bound at all. e.g.:

$ ./python -c "import socket; socket.socket()"
-c:1: ResourceWarning: unclosed <socket.socket object, fd=3, family=2, type=1, proto=0>

Perhaps we should be more discriminate and only warn when either bind(), listen() or connect() had been called previously? What do you think?
