Card-marking is an alternative that I will probably also implement to compare with explicitly recording inverse pointers.  I'm not a big fan of card-marking because it imposes some constraints on the object representation (object alignment on card boundaries, or BIBOP) and the scanning can be more expensive due to the conservatism of the cards.
