    Research direction

    Start at multiprocessing.Pool.join and compare the attached cpython_timeout.patch and cpython_raise_timeout.patch. Determine which timeout and expiry behavior is intended; the work is complete when Pool.join supports that behavior consistently and the relevant multiprocessing tests cover it.
