As I was using Nautilus to load up some photos from my camera the clock
froze. I managed go get to the desktop I had top running in and stop it

top - 15:59:18 up  8:05,  1 user,  load average: 5.57, 2.11, 0.89

I notice that 'system' cpu usage is pretty high. I guess I need to run
top without stipulating -u chris.
