I saw the behaviors as follows:
threading.Threadandmultiprocessing.Processdo not raise to the main thread.multiprocessing.Poolandmultiprocessing.pool.ThreadPool(this is not documented at all) leave zombie threads.
The results show that concurrent.futures is the best choice for threading and multiprocessing in Python!
I did this experiment on Python 2.7.9, and Python 2.x does not have concurrent.futures, so I installed it by pip command pip install futures.
