    Note: not sure whether this issue belongs as a "behavior" or an "enhancement"

    In IDLE:
>>> def print_a_test_string():
     print "test"

    >>print_a_test_string()
    test
    >>threading.Thread(target=print_a_test_string).start()
    test
    >>multiprocessing.Process(target=print_a_test_string).start()
    [test is not said]
    >>
    Running this example in the standard interpreter will print "test" all three times (in current thread, new thread, new process). (Acutally, I got an AttributeError and had to work aroung it using functools.partial(print, "test"))

    OS: Windows XP
