Thanks to the usual layers of baffling renaming via macro after macro, I missed object.c's PyObject_CallFinalizerFromDealloc(), which both respects and sets the "am I finalized?" flag regardless of how, e.g., an object with a __del__ ends its life (and possibly resurrects).

Speaking of which, I no longer believe that's true.
