I'm not sure that it is related to threads. It looks, like some of your
processes do not exit properly, and then thread-join is blocked.
I've modified your example, again. It runs perfectly. And during its
work, you could call "M-x list-threads" and see how the threads are
created and die.
Best regards, Michael.
