I've been wondering about this for some time now but I was not really sure 
if this was a real problem with the system or just a perception issue. 
Whenever disk I/O occurs this seems to impact the interactive behavior of 
other applications quite considerably. In some cases I see apps locking up 
for up to two or three seconds because a second process accesses the disk.
