One problem with rolling it into cpuacct is that some of the
statistics have a 1:1 association with the hierarchy being throttled.
For example, the number of periods in which throttling occurred or the
count of elapsed periods.

If it were rolled into cpuacct the only meaningful export would be the
total throttled time -- perhaps this is sufficient?
