I've never looked at the code, but I would have thought that
there would be some sort of block-sorting/elevator-algorithm step
in between "this list of blocks need to go to disk" and "disk
drive: seek to xyz; write blocks nnn to nnn+m". Isn't there?
If there is, then this reversal probably doesn't matter much, if
all it does is pessimize an in-memory sort.
