[issue20800] Cannot run gui tests twice.

[Ned Deily]

Ned Deily added the comment:

For what it's worth, I don't see the problem on OS X (haven't tried it recently on a Linux system), so it might be a Windows only issue. It's become clearer that some test combinations can only be safely run with the regrtest -j option to run them as separate subprocesses. I Does "-m test -j2 -ugui test_ttk_guionly test_ttk_guionly" help?
