Summary: sysctl(8) value kern.cp_times is inconsistent with

cpu-consumption-kern.cp_times.sh
I have a process that uses 100% CPU, pinned to one CPU, according to top(1).
kern.cp_times, however, shows that CPU use frequently changes from one CPU to
another. No specific CPU appears to be in use consistently, according to
kern.cp_times.
Please see the attached program.
This program follows the algorithm used by xfce4 CPU use plugin
sysutils/xfce4-cpugraph-plugin, which also shows incorrect CPU use as a result.
kern.cp_times CPU use data appears to not match top(1), which seems to be
correct.
