    So if that is the case what bounds your memory usage - can a busy box end
    up with thousands of work queue slos used ? It sounds like your model is
    perhaps wrong - if there is a continual stream of work maybe you should
    simply have a kernel thread to handle it if it cannot be deferred
    - remember ldisc code is able to sleep in most paths.
