  If there's any explicit pointer manipulation, these conditions
aren't sufficient, because an object can be pointed to in more than
one place.  For instance, if I have two objects (A and B) sharing
pointers to object X, then object X should be destroyed (assuming no
other references) when both A and B have been destroyed.
  Personally, I prefer controlling my own data structures...leaving it
up to a garbage collector has always seemed a little sloppy to me.
