This looks like a DIY serialisation of exceptions. Does it work for all exception types? What if the args to the exception constructor are not just the msg string?

…1715) I added _Py_excinfo to the internal API (and added its functions in Python/errors.c) in gh-111530 (9322ce9). Since then I've had a nagging sense that I should have added the type and functions in its own PR. While I do plan on using _Py_excinfo outside crossinterp.c very soon (see gh-111572/gh-111573), I'd still feel more comfortable if the _Py_excinfo stuff went in as its own PR. Hence, here we are. (FWIW, I may combine that with gh-111572, which I may, in turn, combine with gh-111573. We'll see.)
