Python multiprocessing Queue failure

Question

I create 100 child processes

proc_list = [
    Process(target = simulator, args=(result_queue,))
    for i in xrange(100)]

and start them

Answer 1

The multiprocessing.Queue is said to be thread-safe in its documentations. But when you are doing inter-process communications with Queue, it should be used with multiprocessing.Manager().Queue()
