[Python-Dev] sharing sockets among processes on windows

Great.  I was about to write unittests for my patch, when I found out that I wanted to use multiprocessing to run them.
So, I decided that the tests rather belonged in there rather than test_socket.py.  This is where I stumbled upon code that multiprocessing uses to transfer sockets for unix.  I need to read that code and understand it and see if it can be persuaded to magically work on windows too.

I´m interested in contributing a patch to duplicate sockets between processes on windows.
Tha api to do this is WSADuplicateSocket/WSASocket(), as already used by dup() in the _socketmodule.c
Here´s what I have:

Just in case anyone is interested, we also have a ticket for this in Twisted: <http://twistedmatrix.com/trac/ticket/4389>. It would be great to share code as much as possible.
