Bletch!  Well, so much for allowing implementations which occasionally
compact the heap.  If you're counting on the same address (or pointer
value - however they are scaled) to mark the same object each time,
you're probably asking for trouble.  If you need to mark a specific
data object, it is better to _explicitly_ mark it.
