sys.exit(1) will exit the tk and the other threads running. But all Processes triggered will stay alive in memory (I still see the logs file fill up).
To be more accurate:
python Main.py trigger process python schdule.py that trigger process python start.py I see logs in start.py
On the other hand not using TK, and killing the command line with X button
Leave no process alive - not accurate, they will keep on running until die with exception in a print statement / some OS error things... WHY ?
