Follow-up of issues:

  • issue bpo-30110: test_asyncio reports reference leak, forgot to shutdown concurrent.futures.ProcessPoolExecutor()
  • issue bpo-30171: Emit ResourceWarning in multiprocessing Queue destructor

I propose to emit a ResourceWarning warning in concurrent.futures executor destructor if it wasn't cleaned up properly, if shutdown() wasn't called.
