If tomorrow Python allows to run two interpreters in parallel (see bpo-40512: "Meta issue: per-interpreter GIL"), I don't think that it will be safe to execute object finalizers of a subinterpreter from the main interpreter in Py_Finalize(). IMO subinterpreters must be finalized manually by the programmer, since it's too tricky. The safest option is to display a warning in Py_Finalize() if there are running subinterpreters.
