Incidentally, do you think it would be possible to implement a kind of 

btree_for_each_entry(e, ...) {
	do something with e
}

macro or function/macro combination? You seem to be doing a recursive
walk across the tree, would it be useful to have a linked list at the
lowest level of nodes to be able to iterate more easily?
