What do you mean by integer counter? You have to store a reference to
the object when object-address is first invoked on it; then you might
as well store the object in a list and simply mark it conservatively.
(and then you have to add support to maintain the list weakly --
argh).

The value is only intended for human consumption (i.e. debugging)
