And like the `concurrent.futures` module for `concurrent.futures.ProcessPoolExecutor` but not for `concurrent.futures.ThreadPoolExecutor` (see above), the `multiprocessing.pool` module seems also affected by a similar problem for `multiprocessing.pool.Pool` (process pools) but not for `multiprocessing.pool.ThreadPool` (thread pools).

Indeed the following code:

    import multiprocessing.pool
    
    class A:
        def f(self):
            print("called")
    
    class B(A):
        def f(self):
            pool = multiprocessing.pool.Pool(2)
            pool.apply(super().f)
    
    if __name__ == "__main__":
        B().f()

raises the following exception:

> AssertionError: daemonic processes are not allowed to have children
