Python GIL issue when simulation is exiting

[christophe0606]

It is a minor issue because the demo FVP_Audio worked and the output audio file was generated.
I have set AUDIO_STREAM_DURATION to 1 so the simulation is stopping after one second of output is generated.

And it looks like exiting the simulation is causing some troubles (Python 3.12 used):

Audio streaming started...
Audio streaming stopped.
Info: /OSCI/SystemC: Simulation stopped by user.
Fatal Python error: _Py_GetConfig: the function must be called with the GIL held, 
after Python initialization and before Python finalization, but the GIL is released (
the current Python thread state is NULL)
Python runtime state: initialized

Here are the error details (on Windows but I edited the path before copying in this issue):

AFAIK this seems to be the same problem reported here: ARM-software/SDS-Framework#206 and this should be fixed in the upcoming FVP v11.32 release.
