Oh, good - I was wondering how I'd missed this when doing initial
testing on rbtree code.  If you're removing features like this you
really need to call it out in the changelog, this is quite a nasty
regression as we can easily end up doing a couple of orders of magnitude
more I/O on a slow bus than we were expecting to.
