I've done this and uncovered some problems.  When removing all objects
from a map with free_all_objects(), a button is removed, then something
else is removed that is on top of another button, that other button is
updated via update_button(), and update_button() complains loudly
because the first button is still in the get_button_links() list, but
already freed.  This wasn't triggered before because update_button()
only checks op->count but not QUERY_FLAG (op, FLAG_FREED).

I'm also wondering how move_all_objects() is supposed to work because
it doesn't update the button links.
