I did a quick look over it on the plane today and it looks quite nice
to me.

I guess there are no patch descriptions left anywhere?

Otherwise some of the patch might need some minor polishing, e.g.
the patch moving over from the radix tree to the btree leaves the
radix-tree implementation in, which gets removed in the next patch
which has otherwise unrelated changes.

The btree implementation btw worries me a little, I wonder if we need
a test harness to make sure it's correct for all corner cases.
