_json currently uses a few static locals for caching of PyUnicode and one Exception object.  This patch aims to move them to the heap.

Apologies if this isn't the right way to track subinterpreter issues, I took a look at issue36876 but it seemed like a meta issue to me.

Hi Victor, I'm re-using this issue as I'm doing a similar change to compile.c. I hope you're alright with that.

KJ, please create a new bug for compile.c. bpo's are cheap to create.

Hi Christian and Victor, thanks for the advice! Points taken. I'll keep in mind to create a new issue for similar things in the future so things are less confusing for everyone.

The new issue for this is Issue44156.
