    It does, thanks.

    A concern which I have about the CKRM implementation is that the patches
    which have been sent out appear to be simply the "core" of CKRM, plus
    minimally-intrusive hooks. I have the impression that this core will not
    be terribly useful to real-world users and that follow-on patches will be
    required to add more functionality and to wire up more instrumentation and
    control points.

    I would not like to be in a situation where we merge the "core" patch, but
    the as-yet-unseen follow-on patches which make CKRM useful and complete end
    up creating a big unmaintainable mess. We end up not wanting to go
    forwards and being unable to go backwards.

    IOW: I think we need to see a reasonably-close-to-final implementation of
    CKRM before we can take it much further.
