This code runs 8 threads in parallel each showing an iwidget (pushbutton or anything else, doesn't matter) and after ~1 minute it crashes with:

As far as I know, Tk isn't thread safe. So your approach is fraught with danger to begin with. It would be better to have one thread for the GUI and separate threads to do the work, if needed.
