In Linux you can easily inherit the global Value object in forked
processes, but it's not that hard to support Windows, too:
if __name__ == '__main__':
how_many_spams = Value('i', 1)
args = (how_many_spams,)
p1 = Process(target=update_brain, args=args)
p2 = Process(target=chat_with_friends, args=args)
p1.start()
p2.start()
On Windows, multiprocessing has to launch a fresh interpreter, import
the main module, and pickle/pipe the args to the new process. Setup
code that should only run in the main process has to be guarded with a
__name__ check.
