Victor, what is your opinion of running 'from test import autotest' in a standard python shell window, opened from an icon, as opposed to IDLE's shell?

>  many tests fail just because of IDLE.

We cannot know what to blame on IDLE without a proper control experiment.  I updated my Win10 repository, rebuilt python 3.7, ran the tests from the command line, and all passed (thank you for making this routine).  I ran autotest in a Python console and saw a new resource warning from one of the async tests and 3 failures.  I cannot say what they were because when the test finished, the window closed (crashed), which is a metafailure.  I will rerun and try to identify the error as they occur.

Should we reopen this issue or open a new issue, to fix problems not due to IDLE, or remove the entire suggestion to use autotest, and remove autotest itself?
