[PATCH] Tweak VM dirty thresholds

The below patch on 2.5.12 takes the 'dbench 32' throughput on a
1024 megabyte machine from 35 megs/sec up to 125 megs/sec.
That's on the second run.  The first run is much slower because
the ext2 bitmaps aren't in cache.

Presumably, s/60/80/ will take it even higher.
