I guess I probably ought to review this. All the code changes look
sensible and appear correct by eyeball. Whether they are really needed
or, indeed, are /all/ that is needed is far from obvious. I could at
least build the tree and test that it runs ok. Are you able to provide
any special instructions needed to achieve that? (esp the latter).
