New submission from Jan Kanis: While fixing #18132 I noticed that when closing the turtledemo window an exception is thrown (and ignored) because the __del__ tries to catch a TclError exception, but the TclError global has already been deleted and set to None.
I could only reproduce this in my self built pydebug build, at least on revision dfcb64f51f7b, but not on the v3.3.2 tag. (compiled with --with-pydebug on linux x86-64) traceback: me@mymachine ~/d/cpython> ./python -m turtledemo BYE!
