That looks good and might come in handy if khubd ever becomes multi-threaded. Until then it may not be needed, since khubd is the only thing that changes the tree topology. (Saying that this algorithm locks a subtree isn't quite right, however. It locks the _top_ of a subtree but nothing below that.)
