Just for the record: Ryan May's example in this thread, that uses pipes, inspired me to try pipes as well, instead of queues (multiprocessing.Pipe instead of Queue) and the "hanging problem", i.e. the problem that Ctrl-C interrupted the program, but it had to be killed to stop, disappeared. I can fix the script that I sent in message [1] and provide it, if there is interest. (Currently I have fixed only the version that is within sfepy). thanks! r.
