I didn't see the failure recently, I close it.

Moreover, Python 2 is not longer supported.

[issue36339] test_ttk_guionly: test_traversal() fails randomly on AMD64 Windows8.1 Refleaks 2.7

[Terry J. Reedy]

Terry J. Reedy  added the comment:

My guess is that the failure is in event_generate(key), as in #36286.  If so, 
this is a duplicate of the latter.

How often have you seen a failure?  For event_generate(''), etc, the 
failure time in my test script varies from 1000 to 100_000 tries and there have 
been no build-bot failures reported to me.

Now that I can make the failure happen, I still need to experiment with trying 
to stop it.
