[issue7318] multiprocessing should not wait endlessly

New submission from Antoine Pitrou <pitrou [at] free>:

SocketClient() in multiprocessing.connection loops endlessly when the
connection is refused. It shouldn't, and instead use a timeout.
This is especially annoying since SocketClient() can be called as part
of finalizing an object, which makes debugging very annoying (see
issue7060).

Ok, this is now committed to all 4 branches. Amusingly, it seems to
solve the test_multiprocessing freeze/failure problem in py3k...
(I still hope you can find some time to make multiprocessing more robust
and less baroque inside!)

So do I and I'm sorry I haven't been able to yet. First on my list is
a total test suite scrub.
