It took me 2 months, but I finally identified why *sometimes*,
test_logging fails with warning about threads. It's exactly because of
the weak socketserver.ThreadingMixIn which leaves running threads in
the background, even after server_close(). I just opened a new issue:

"socketserver.ThreadingMixIn leaks running threads after server_close()"
