Oh, this test only "leaks" dangling processes and threads because PR 2841 was too strict. The problem is that multiprocessing.Pool has thread attributes which hold references to the pool: reference cycle. I don't see any easy way to break these cycles; since I don't understand if a poll is still supposed to be usable after terminate() or not.

Anyway, my intent here was to do a first cleanup. So I modified my PR 2841 to call support.gc_collect() to break reference cycles.

If someone wants to break reference cycles, please open a new issue. IMHO this issue already became enough complex :-)
