Last month I continued looking into race conditions in threads and
threads::shared. I have now reached the point where the threads-related
test suite can run cleanly under 'valgrind --tool=helgrind / drd' and the
threads-related tests can be repeatedly run in 40 terminals for days
without issue.

I've pushed the work as GH ##24439.

SUMMARY:
     20:21 GH #24258 dist/threads/t/free.t: Rare test failure in debugging build on FreeBSD
