Fail PyGILState_Ensure() If Finalizing? #124622
Description
Feature or enhancement
Proposal:
Once the runtime or current interpreter starts finalizing, we currently exit or stall the current thread as soon as it tries to acquire the GIL, via PyThread_exit_thread() (or PyThread_hang_thread() after gh-105805). That includes in PyGILState_Ensure(). However, in the case of the latter it might make more sense (i.e. friendlier) for the call to fail instead of exiting/hanging the current thread.
FWIW, this is a hypothetical situation I noticed while looking at pystate.c. Also, the same scenario would be affected by gh-124619.
