[issue31233] socketserver.ThreadingMixIn leaks running threads after server_close()

[STINNER Victor]

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

The current code leaks memory since it never clears threads which completed. We need a cleanup function similar to ForkingMixIn.collect_children() which is called by handle_timeout() and service_actions().

We can check if a thread is alive: thread.is_alive(), to decide to remove it or not.

Moreover, maybe we should keep a list of weak references?
