Will bump up the version when I refresh the change.

I think I can see your point: there is potentially better information
about the power consumption of the CPU beyond the time it was busy.
But please clarify: is your complaint the lack of use of this
information or are you arguing for a deeper integration into the
scheduler (I.e. implementing it as part of the scheduler rather than
an independent thread) or both?
