Hum...  I didn't realize that it can exist in that state.  I'm not sure we want
to have two ways of managing a ref count on this object.  That seems overly
complicated.  Maybe we should wait until oilpan lands before implementing this
API.  I don't see a clean way of doing it given our current memory management
techniques.
