[docs] [issue17674] All examples for concurrent.futures fail with "BrokenProcessPool"

[Antoine Pitrou]

Antoine Pitrou added the comment:

This is not the example code. The example code uses a main() function which is guarded by a "if" block:

if __name__ == '__main__':
    main()

See http://docs.python.org/2/library/multiprocessing.html#windows for explanations.

Also, perhaps the concurrent.futures docs could point to that paragraph.
