I didn't write the respective code in Cython, but there's a comment next to
it saying

    /* Don't use Py_AtExit because that has a 32-call limit
     * and is called after python finalization. */

So Py_AtExit() may or may not be what you are looking for.

Also note that Py3 has a C-API mechanism for safely cleaning up (and
potentially unloading) modules, which likely is what you are looking for
anyway.

Personally, I find it a matter of developer time (basically "why write C
when you can write Python?"), but your mileage may vary.
