'ssl' in dir(socket) will return 0, because the entire SSL stuff in
socketmodule.c is #ifdef'd out.
print urllib.urlopen("https://www.sf.net/").read() raises

You seem to still have SSL compiled in. Be sure to replace your
_socket.pyd with the one without SSL. Using "python -v" helps tracking
down which module really is loaded.
