This could have gone in the commit message itself. I believe (but I'm
not 100% sure) that this issue started occurring when fully random
configurations started being tested. Indeed before that we were not
testing configurations with threads enabled but not NPTL, I believe.

Anyway, the fact that the issue existed in September 2022 means we need
to backport this fix to our stable 2023.02.x and 2023.05.x branches,
which is really the information that we need to have.
