So what is causing this bug in 3.10 is the following stack:
thread_entry_point()
PyGILState_Ensure()
PyGILState_Release()
...
PyGILState_Ensure()
The core issue is that PyGILState_Ensure is getting called while the tstate
itself is in the process of being destroyed. This causes an invalid state and
eventually results in a segfault or "Fatal Python Error."
I think the most robust fix is to allow re-entrancy to
PyGILState_Release/PyGILState_Ensure. If that is prohibitively complex and/or
is not specified to be allowed, I believe the most robust fix is to avoid using
sqlite3 destructor callbacks to DECREF Python objects.
