[issue1702036] Make Turtle thread-safe so it does not crash

[Alexander Belopolsky]

On a closer look at the first post, I see that there are two parts to the issue.  The first is indeed a duplicate of #6639, but the second is thread related.   I am attaching the OP's code in a script file for convenience.  Running ninja.py under python3 produces 

RuntimeError: main thread is not in main loop

in every ninja thread.  This looks like tkinter limitation, but I think it is possible to work around it in turtle, so this is a valid feature request.
