Okay, I don't know, maybe, but I don't think it's gonna buy much. We
need boundary check in the distance testing function anyway in case
someone calls in with out-of-bound nid's and not having distance table
is just a degenerate case of the generic sanity check, so there really
isn't much to be gained by allocating dummy table.
