[issue38106] [2.7] Race in PyThread_release_lock on macOS - can lead to memory corruption and deadlock

I can confirm that I have the deadlock because of the reason described above. When I change the PyThread_release_lock source locally to signal before releasing the mutex, then my deadlock does not occur anymore. I have tested it on a heave multithreading model.
