sleep

I'm using Ubuntu 9.04 64 bit on an AMD. It regularly hangs for a few minutes at a time when some of the processes's CPU usage % goes into 'disk sleep'. During that time I can't start new programs and most of the programs on the desktop become unresponsive.

I would rather it didn't hang and my applications remained reliably responsive. Why does this happen and how can I stop it?
