/* These two macros are basicly Py_BEGIN_ALLOW_THREADS and Py_BEGIN_ALLOW_THREADS
* from the other direction. If a Python thread calls a C function
* Py_BEGIN_ALLOW_THREADS is used to allow other python threads to run because
* we don't intend to call any Python functions.
*
* These two macros are used whenever a C thread intends to call some Python
* function, usually because some registered callback was triggered.
* Just like Py_BEGIN_ALLOW_THREADS it opens a block so these macros have to be
* used in pairs. They aquire the GIL, create a new Python thread state and swap
* the current thread state with the new one. This means this thread is now allowed
