Closing for essentially the same reasons as PEP 703: Making the Global Interpreter Lock Optional (3.12 updates) - #155 by davidism. This discussion has begun to go in circles, with new people showing up who are repeating questions and topics that have already been well covered previously.
The developers working on the GIL removal and other faster Python initiatives are all aware of the issues surrounding it, and are taking them into account. Work is being done, and changes are not being made lightly or without consideration.
At this point, discussion about this topic should focus on specific technical points, not high level guesses about how things might work. There is a reference implementation, and years of discussion, to refer to. I’m sure the developers would appreciate more people trying these things out and contributing reports or patches to fix real issues, so please focus further efforts there.
