Numba has a nogil annotation, I'm wondering if we can somehow drop the GIL and what would that imply.

see: JuliaPy/pyjulia#535

In case relevant, new in 3.12rc1:
https://peps.python.org/pep-0684/

PEP 684: A Per-Interpreter GIL
Sub-interpreters may now be created with a unique GIL per interpreter. This allows Python programs to take full advantage of multiple CPU cores.

EDIT: Moved long text here to: JuliaPy/PythonCall.jl#343

I noticed "closed this as not planned" so discussion likely relevant at PythonCall (not here to not split the discussion), if at all, in case something needs implementing.
