Bug report

Bug description:

I occasionally see

UserWarning:ResourceTrackercalledreentrantlyforresourcecleanup,whichisunsupported.Thesemaphoreobject'/mp-gtkzf9rd'mightleak.

warned in the test logs, I suspect test_force_shutdown_workers_dead_workers is the culprit.

It looks like the ResourceTracker was built to warn on re-entrant execution but I think it can be made to work instead.

CPython versions tested on:

CPython main branch
