I think it would address your problem but I don't know if the
name of the flag makes sense. Code around PyInstance_Check()
usually looks like this:
if (PyInstance_Check(obj)) {
PyObject *foo = PyObject_GetAttrString(obj, "__foo__");
...
}
else {
...
}
There is not a lot of code that assumes (obj->ob_type ==
PyInstance_Type) after a PyInstance_Check(). That's encouraging.

I don't know. I think I am trying to a address a deeper problem
here.

Yes, I have that feeling as well. More deep thinking is probably
required. :)
