Jeremy Kloth  added the comment:

While now not as immediately beneficial, I believe that the linked PR would be 
good for the long run.  The ramifications of bpo-11105 meant that the Windows 
buildbots were basically unusable for 5 days.

Realistically, any commit that triggers aborts in the Windows test runs will 
exhibit this problematic behavior.  I'm confident that the PR is in ready-to-go 
form.

Jeremy Kloth  added the comment:

The PR has been successfully run on the buildbots.

Before:
https://buildbot.python.org/all/#/builders/593/builds/58

After:
https://buildbot.python.org/all/#/builders/593/builds/59

With these changes, at least now aborted runs can be seen as direct failures of 
Python's tests instead of just builder exceptions.

To verify the PR, can someone please add the test-with-buildbots label on GH?

[issue44336] Windows buildbots hang after fatal exit

[Jeremy Kloth]

New submission from Jeremy Kloth :

Currently, a stack overflow is causing the debug build Windows buildbots to 
abort (bpo-11105).  Once the regrtest process is terminated, the buildbot test 
process hangs indefinitely waiting for handles to be closed (see msg350191 from 
bpo-37531 for some details).
