[issue12157] join method of multiprocessing Pool object hangs if iterable argument of pool.map is empty

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

I ran with 3.2, winxp with "if __name__ == '__main__':" added after the def statement (without this, process spawned 150 processes before I got logged out) and ()s added to prints. Hung on pool.join as OP said. I could only stop by closing command window as ^C was ignored. Any new test should have a timeout ;-).
