Microsoft already addressed that issue in WinXP, which has fancy hooks to
the disk defragmenter so that there isn't much seeking when booting WinXP
(it does take several days until the defrag happens).  So I agree with
Callum, and also dunno WTR MS is thinking.

Probably readahead adopting what MS did in WinXP would be most effective
but would also violate the most MS patents, as well as requiring hooking
into the filesystem rather more than is wanted.  Something like UnionFS
might work without patent issues, if it could use a file instead of a hard
partition.
