Eugh, that truly is horrible.

Have a look at /proc/stat and section 1.8 of
Documentation/filesystems/proc.txt in the Linux kernel tree.
To be honest, getting CPU 'usage' is pretty pointless as it's either
busy, idle or busy waiting on IO. You should be using loadavg really
as instantaneous CPU usage tells you nothing.
