Research direction

Start by reviewing the original BPO issue 36133 and the ThreadPoolExecutor and ProcessPoolExecutor entry points in the standard library. Clarify the intended dynamic worker-count behavior and its limits before identifying the relevant tests. Done should be a decided, documented behavior with passing coverage for both executors.
