I confirm that some tests using threads hang under very low memory
condition. At bootstrap, Python doesn't handle correctly all
exceptions when starting a new thread. The "parent thread" waits until
the "child thread" completes, which never occurs because the thread
already completed.

I don't think that it was my regression, it probably exists since
Python 2 and maybe before. I'm not interested to touch this fragile
part of Python. It's maybe easy to fix the issue, I don't know.
