[issue38680] PyGILState_Release does not release gil correctly, resulting in deadlock

The issue here is that the behavior between Python 3.6 and 3.7 has changed.

Our code runs perfectly fine with 3.6. We release the lock each time our functions get out of scope and so we know for sure there is no lock left behind.

Starting with 3.7 GIL is acquired when we start the application, but not by us, maybe internally?, and never gets released; thus the deadlock.
