[issue15646] multiprocessing can do equivalent of a fork bomb on Windows

[Richard Oudkerk]

New submission from Richard Oudkerk:

If the "if __name__ == '__main__'" idiom is not used on Windows you can get the recursive starting of new processes.

This is because importing the main module in a child process starts a new child process as a side effect.

There is a test intended to prevent this and raise RuntimeError instead, but it is currently ineffective.
