    Perhaps a core could provide also as much functionality so that
    Perfmon can be used with an *unpatched* kernel using loadable modules?
    One drawback with today's Perfmon is that it can not be used with a
    vanilla kernel. But maybe such a core is by far too complex for a
    first merge.
