I think I see.  If a reference-holder is expected to drop its reference at a 
specific point, then if the reference is still held at the time of destruction, 
it is a programming error.  Whether to reduce the reference count at 
destruction or leave it permanently above zero is then just a question of 
robustness given the failure of the reference-holder to follow protocol.
