They have two hooks; the above one is just to see if the frame has changed and
tells you if the locals window needs updating, for example.  In the example you
give, I think the frame has not changed but the stack has.  They have another
hook for detecting when the stack has changed which gets set in return_command
and normal_stop.  This latter location uses frame_id_eq so maybe it will fail
for your example (Perhaps it works for Apple, if they have their own unwinder,
although at this point I don't really know what I'm talking about).
