There may be quite a few heuristics, but probably not more than a few k of code. I doubt a userspace heuristic could do a lot better then something built into the hard drive.
As for the train situation, a disk head parking every 2 seconds wouldn't completely kill performance, and I don't see any reason why a userspace demon would be better at handling this situation than an embedded chip. In fact, a embedded chip could probably freeze and unfreeze the disk faster than a userspace demon could, making even pathological situations run better with an embedded chip instead of a userspace demon.
