Oh, David also wrote:

"""
If I can help with testing or builder access or anything just let me know.  It appears that I can pretty reliably trigger the error through just the individual tests (test_daemon_threads_shutdown_std{out,err}_deadlock) in isolation, which is definitely less tedious than a full buildbot run to test a change.

BTW, while not directly related since it was only just merged, and I won't pretend to have any real understanding of the changes here, I do have a question about PR 12024 ... it appears HEAD_UNLOCK is used twice in _PyInterpreterState_LookUpID.  Shouldn't one of those be HEAD_LOCK?
