Attached is this trivial patch. As Merlin says, it needs some more reliability testing. But the numbers are at least reasonable - it *seems* like it's doing the right thing (as long as you turn off write cache). And it's certainly a significant performance increase - it brings the speed almost up to the same as linux. //Magnus
