Eryk's answer is actually much more useful than the documentation. I've
read that documentation many times, but always decided not to use py_object
because I couldn't figure out what it would actually do...

(I still probably won't use it because IME by the time I'm using ctypes and
PyObject* together I usually need manual control over refcounts, but it's
nice to know what it actually does.)
