FYI, as of 3.11 we "freeze" most of the [pure Python] modules that are imported during startup. (See gh-89183.) The idea is that we minimize the amount of disk I/O...

We still have a bunch of "global" C variables (static globals, static locals, maybe thread-local storage) in our code-base that break the isolation between interpreters. I added [Tools/c-globals/check-c-globals.py](https://github.com/python/cpython/blob/main/Tools/c-globals/check-c-globals.py) a while...

Also, [Tools/c-globals/ignored-globals.txt](https://github.com/python/cpython/blob/main/Tools/c-globals/ignored-globals.txt) is a bit out of date (some vars have been removed, renamed, or moved to another file). That should get cleaned up. It might also make sense to...

Thanks, Vinay!
