tl;dr Let's exploit multiple cores by fixing up subinterpreters, exposing them in Python, and adding a mechanism to safely share objects between them.
This all sounds really cool if you can pull it off, and shared-nothing threads do seem like the least impossible model to pull off. But "least impossible" and "possible" are different :-). From your email I can't tell whether this plan is viable while preserving backcompat and memory safety. Suppose I have a queue between two subinterpreters, and on this queue I place a list of dicts of user-defined-in-python objects, each of which holds a reference to a user-defined-via-the-C-api object. What happens next? -n
