Hm, what do you mean when the C object is destroyed? The typical way to
do bindings is to store a pointer to your native object using user_data
on the surface/font_face/whatever, and use the user_data destructor to
clean up your wrapper object. Doing that should avoid any problems when
refs are kept to the C object outside of your binding's knowledge. The
only complexity arises from then needing to do refcounting on your
wrapper object as well, to know when to release the final cairo ref.
