[issue34609] Idle Unitest

[Cheryl Sabella]

I have Python 3.6.5 on Ubuntu 18.04.  Initially, I was unable to recreate the issue.  However, issue33065 from 4 months ago has the same trace (except on a different import), so I tried stepping through debug using the minimal example that Terry gave and successfully reproduced the trace.

I then tried a new build of 3.8 on Ubuntu and was also able to reproduce by using 'step' while in debug.

I also was able to recreate using 'step' under 3.6.3 on Windows 7.

Note: At one point while stepping, the debug window shows a KeyError on unittest.  You'll see it yourself, but it is interesting.
