Delayed allocation still performs a lot better here than the v3
"immediate" allocation. In addition, tree balancing operations are
performed on flush as well, so what you get on disk is basically an
almost-optimal tree. Of course, this will change a bit over time, but
with v4 it takes a lot longer for that to happen than with v3 afaict.
There _has_ been some worthwile development in the meantime : )
