Probably not.  Because precise pointer locations are not known for
the stacks, they are treated conservatively, and any objects
potentially referenced from the stacks are pinned in place by the
GC.  It would be impossible to update references to your reallocated
object if those references live in the stack because we do not have
precise information for stack pointer locations.
