If you need a well defined environement, run your test in a subprocess. Depending on the random function, your test may be run with more threads. On BSD, it changes for example which thread receives a signal. Importing the tkinter module creates a "hidden" C thread for the Tk loop.
Does it mean that non-thread-safe tests can't be run using a GUI test runner that is implemented using tkinter?
