[issue31901] atexit callbacks only called for current subinterpreter

[Petr Viktorin]

Petr Viktorin <encukou at gmail.com> added the comment:

When you destroy a subinterpreter before Py_Finalize is called, Python can't start calling its atexit callbacks – they no longer have a subinterpreter to run in.

Therefore I think callbacks for a particular subinterpreter should be called when (and only when) that subinterpreter is destroyed. Regardless of whether it's the main one or not.
