This is the culmination of PEP 684 (and of my 8-year long multi-core Python project)!
Each subinterpreter may now be created with its own GIL (via
Py_NewInterpreterFromConfig()). If not so configured then the interpreter will share with the main interpreter--the status quo since the subinterpreters were added decades ago. The main interpreter always has its own GIL and subinterpreters fromPy_NewInterpreter()will always share with the main interpreter.(FYI, I've split up the original gh-99114 into multiple PRs, with this one being the final one in the chain.)
