returning to this after too long away, I've committed what seems like
the most sensible fix:
which is different from yours. It only starts fast-RA when the
dhcp-range in question has never been used before. This satisfies the
original aim of 0a496f059c1e9d75c33cce4c1211d58422ba4f62 but eliminates
the possibility of the infinite loop.
Does that work for you?
