Con Kolivas returns with a new scheduler

Good question! The desired property here is mainly "not CFQ", since the
default CFQ scheduler seems to behave badly (wrt IO latency) with cheap
SSDs. See for example http://forum.eeeuser.com/viewtopic.php?id=23580 .

The noop scheduler is also sometimes recommended, but the linked thread
suggests it may suffer from IO starvation since it doesn't do any balancing
between processes.

[ it also recommends the following, which I haven't tried:
echo 1 > /sys/block/sda/queue/iosched/fifo_batch
