That very well may be... but my experiments to date seem to indicate that
the address for a frame doesn't seem to change simply because slots have been
added, but does seem to change after events that would imply that garbage has
been collected. (more snooping remains to be done...)
Interesting. They could be using forwarding pointers and postponing
fixing up the pointers until the next GC (when it has to update a lot
of pointers anyway).
