Sorry, something went wrong.
...as opposed to storing it in PyRuntime. Storing it in PyRuntime is fundametally wrong, as its state contains references to Python objects. Those objects (tuples and strings) can (and will) be picked by various subinterpreter clean up code, leaving PyRuntime with broken pointers.

There was a problem hiding this comment.
I think having a lock isn't necessary in 3.12 as we're muving this struct to InterpreterState. Local state modification will be protected by the GIL.
