I'm not sure I understand your diagnosis. modules_per_index (and
PyState_FindModule) is per-interpreter so we already have a
per-interpreter state here. Something else must be interferring.
Note that module state is just a field attached to the module object
("void *md_state" in PyModuleObject). It's really the extension modules
which are per-interpreter, which is a good thing.
