/* In the mutable address map MAP, associate the addresses from START
to END_INCLUSIVE that are currently associated with NULL with OBJ

In particular, "currently associated with NULL" is the key.
My understanding now is that this data structure is designed to be
built bottom-up. So, I think that this is a bug in the caller, and
that the test I wrote is actually not correct.
Of course, it would be ok to change addrmap's contract. But, if we
want to do this then I think we would need more tests covering other
BTW, addrmap is nice code. It has all the hallmarks of the Blandy
