We have quite a bit of global state the runtime that effectively breaks the isolation between interpreters. Some of it exists as "global" C variables (see #36876) and the rest as fields on _PyRuntimeState. The offending state should be moved to PyInterpreterState. See Include/internal/pycore_pystate.h for the _PyRuntimeState and PyInterpreterState structs. |

FYI, I've already started some of this work: * #36737 warnings * #36854 gc * #33608 pending calls * #10915 & #15751 gilstate Other bits I'm planning on: * the rest of the global "ceval" state * the memory allocators * the GIL Note that, to make the GIL per-interpreter, we can't have any remaining runtime state shared by interpreters (unless it is protected by its own locks). |

In conjunction with #36876, there are a bunch of currently ignored globals (in Tools/c-globals/ignored-globals.txt) that should actually be moved to per-interpreter runtime state. This mostly applies to any globals that point to one or more objects, since objects must not be shared by interpreters. |
