Actually the kern.cp_time variable might be better if you want
idle/kernel/user values. It returns a long cp_time[CPUSTATES]; the
states are listed in <sys/resource.h>. Top calculates percentages by
keeping the previous interval values, calculating diffs, totaling up
the diffs, and setting percentage[cpustate] = diff[cpustate]/totaldiff.
