But I don't see a clean way to interface such a module in the system at
this time. Needs hacking. Oh well :)

Or a program that's runnable once and generates timing information for
each block on the drive. It would take a while to run, but it would be
interesting to see whether or not the benefits would be substantial. A
userland program could then feed it to the sorting module. Yet another
research project.

Or even a relatively simple expert system sorter would do. This would also
be a good tool to demonstrate the possibility of starvation (shortest seek
time first) when sorting blocks. All in all, I think this will be a Good
Thing.
