As reported initially by @rad-pat in #6084, the following script causes a deadlock. ``` from concurrent.futures import ProcessPoolExecutor class ObjectWithPickleError(): """Triggers a RuntimeError when sending job to the workers""" def __reduce__(self): raise RuntimeError() if __name__ == "__main__": e = ProcessPoolExecutor() f = e.submit(id, ObjectWithPickleError()) e.shutdown(wait=False) f.result() # Deadlock on get ``` This is caused by the fact that the main process is closing communication channels that might be necessary to the `queue_management_thread` later. To avoid this, this PR let the `queue_management_thread` manage all the closing. https://bugs.python.org/issue39104 Automerge-Triggered-By: @pitrou
