You're right, I have finally come up with a better solution than those
I have anticipated. After initialization of embedded python in the
application I release GIL (with PyEval_SaveThread) and properly wrap
all calls to python API with PyGILState_Ensure and PyGILState_Release.
As a result most of the time no thread holds GIL - so any thread can
access python interpreter without getting stuck.
