First thing we need to work out is whether it is a CPU scheduler thing
or if it is a VM/MM/block/fs latency problem.

- How much memory do you have?

- Are your disks runnning in DMA mode? (run hdparm /dev/hda)

- Send `vmstat 1' traces from when the problem is happening.

- If you nice up the X server, does that help?

- Try setting /proc/sys/vm/swappiness to zero

- Try decreasing /proc/sys/vm/dirty_ratio to 15
