The problem is that socketserver.ForkinMixin doesn't wait until all children completes. It's only calls os.waitpid() in non-blocking module (using os.WNOHANG) after each loop iteration. If a child process completes after the last call to ForkingMixIn.collect_children(), the server leaks zombie processes.

The server must wait until all children completes. Attached PR implements that.

The bug was be reproduced with the attached forkingmixin_sleep.patch.
