  1. [3.11] pythongh-106883 Fix deadlock in threaded application 

    When using threaded applications, there is a high risk of a deadlock in
the intepreter.
It's a lock ordering deadlock with HEAD_LOCK(&_PyRuntime); and the GIL.

It has been suggested to disable GC during the
_PyThread_CurrentFrames() and _PyThread_CurrentExceptions() calls.
