Comment 100 for bug 985661

Run top to see what is running and what CPU it is using and total CPU it has used over time.
I do not know the list of tasks that typically run with the desktop edition, as I don't use it.
If you are not doing anything with the computer, it still has operating system overhead to deal with. The load average code runs in the heart of the kernel, and it doesn't know anything other than if a CPU is in use or not busy at the 5 second sample time.
