maybe we could add an option, defaulting to off, that would have a server
periodically walk the tree from the root to itself, checking for above/below
deltas across each delegation, and checking for lameness?

in other words, are we looking at this wrong, saying that lameness is a
parent's problem?  maybe if we say it's a child's problem, and do what we
can to help zone operators run better child zones, our part can be bigger?
