threads and subprocess.call

[Skaperen]

that's certainly "a way" to run the commands in parallel. if my objective were only that, it is like i would do it very similar to this (though not likely in a comprehension). i need to do it in threads so my question is as posted. if i need to avoid threads, it could be much harder to do. i might have to use multiprocessing. i have not put much thought into this, yet, and won't until i know which directions to focus on.
