I can confirm the patch works in Windows.  Regarding the 0.0.0.0 issue, 
perhaps we can compromise on something like this:

% svn diff connection.py
Index: connection.py

         self._socket.bind(address)
         self._socket.listen(backlog)
         self._address = self._socket.getsockname()
+        if self._address[0] == '0.0.0.0':
+            self._address[0] = '127.0.0.1'
         self._family = family
         self._last_accepted = None


That way, we still support binding on all addresses, and self._address 
will always represent a connectable end-point.  Thoughts?
