The handles are usually still pointers.  First you copy the object to
the other heap, then later you scan it, copy the objects that the first
objects points to, and update the pointers in the first object to point
to the new locations.  This is described pretty well in the SICP chapter
on metacircular evaluators (mitpress.mit.edu/sicp).
