[Sussex] processor usage as shown by top

[Tony Austin]

If I look at top while running a compile I see in the heading line:

Cpu(s):  97.0% user, 3.0%, system, 0.0% nice, 0.0% idle

In the body at the top of the list I see cc1 using about 12.0% and nothing
much else reporting any processor usage.

I would have expected the list of percentages to add up to roughly the
"user" figure.

Can anyone explain what  these numbers mean?
