[issue3807] _multiprocessing build fails when configure --without-threads

[STINNER Victor]

STINNER Victor <victor.stinner at haypocalc.com> added the comment:

I don't understand the usage of _save argument of conn_poll() function
(of the _multiprocessing module). Here is a patch to remove it. I first
wrote this patch to try to compile _multiprocessing without thread
support (which is stupid because _multiprocessing requires semaphore).

Just ignore my patch if the _save is used somewhere.
