    hm, there must be some misunderstanding here. That mlock is /only/ once
    per the lifetime of the whole 'head' - i.e. per sys_async_register().
    (And you can even forget i ever did it - it's 5 lines of code to turn
    the completion ring into a swappable entity.)

    never does any MMU trick ever enter the picture during the whole
    operation of this thing, and that's very much intentional.
