I actually have a related question. I remember that weak refs weren't
allowed to ressurect the object. However, with the weak ref callbacks
running from dispose, and dispose being allowed to ressurect the object,
why can't weak refs ressurect?

Maybe weak ref callbacks should be moved to finalization?
