    It wouldn't need to convert the whole Frameworks layer into C, just
    enough to manage the suspend state.

    Anyway, I think there's been enough arguments against even the concept
    of opportunistic/auto-suspend, and I for one will object with a NAK if
    Rafael send this to Linus.

    The whole idea of segregating userspace like that, and not letting
    runnable thing run is very ill considered indeed.
