Here are contest benchmarks for 2.5.59-mm10 and
2.5.59-mm10 with the anticipatory I/O scheduler in the
current experimental patch form. Needs tuning.

Sorry about the message being an attachment. It's hard
to keep it formatted from this crappy webmail.

I went back and checked them because I didn't believe the results the first 
time. These are a clean set of results, and they correlate with the first 
lot. The anticipatory scheduler needs tuning. Note that even noload takes 
longer, but the cacherun isn't. All the disk I/O based loads take longer.
