Taking advantage of Python 3.14 multi threading improvements

[LudwigBloder]

Hi Guys
I really do appreciate the work of the pybind11 team. It helps a lot when dealing with hosting python in my application. However, since my application does have significant performance requirements I wonder to what extend pybind11 already does take into account improvements of Python 3.14 (and beyond) in the multi threading area, especially when dealing with GIL. Is it possible already, and do there even exist proper samples, to use multiple 'python engines' in one c++ application running on separates threats exploiting all these improvements?
