There is also the simplified GIL API, which only requires two function
calls. This is e.g. how ctypes makes sure the GIL is held in callbacks
to Python.
A 'with gil' block could just expand to:
{
PyGILState_STATE _gilstate = PyGILState_Ensure();
/* now we have the GIL */
PyGILState_Release(_gilstate);
}
Nothing else is required. The simplified GIL API makes sure the function
does not deadlock if the caller already has the GIL. The only
requirement is that a call to PyGILState_Ensure should always have a
matching call to PyGILState_Release.
