 For some reason, on my dualcore system, the individual bars for core 0
 and core 1 are in the reversed order, which can be seen by doing:
 
 # cpuset -c -l N /bin/sh
 subshell# while :; do :; done
 
 which puts core N on 100% load. The output of top(1), `sysctl
 kern.cp_times', and /compat/linux/proc/stat show the correct values, but
 the plugin show bar 2-N going to 100%.
 
 I see the same bug when hacking in __FreeBSD_kernel__ and changing
 PROC_STAT to "/compat/linux/proc/stat" in os.c.
 
 I can test this tomorrow on a hexacore box to possibly find more clues.
