It depends: As you cannot "kill" a thread in Python, you need some mechanism
to stop your script another way (is that a python script or
a .sh / .bat ? ... from what you're writing, it seems you're calling some
external entity which just might launch a bunch of processes)

So do you or not control the inner workings of that external script ?

If you don't, then "killing" might be the way as posted / clearly the
methord will change from environment to environment.

  Yeah, it is a Python script, which I preprocess and then load using
__import__(script_filename)
So when I preprocess it, I can add/remove codelines and possibly
add control of the GUI - the original Python scripts will not
know anything about the GUI.
