    Shouldn't the idle governour estimate this already?

    BTW I looked at something like this for networking. There was
    one case where a network benchmark was impacted by deep sleep
    states while processing packets. But in the end it turned
    out to be mostly a broken BIOS that gave wrong
    parameters to the idle governour.
