> but faulthandler_dump_traceback calls PyGILState_GetThisThreadState() which ultimately calls thread.c's find_key() which acquires a lock:

Hum, Python 3 now uses native TLS, not this fallback implementation using a lock. At least on Linux and Windows. I don't know if the fallback implementation is still used (which platforms supported by Python don't provide pthread API?

PyGILState_GetThisThreadState -> PyThread_get_key_value:

* pthread: pthread_getspecific()
* Windows ("nt"): TlsGetValue()
