    How about something as simple as: if process sleeps, and AS scheduler
    is waiting since last request from that process, AS scheduler stops
    waiting immediately?

    In other words, a hook in the process scheduler when a process goes to
    sleep, to tell the AS scheduler to stop waiting.

    Although this would not always be optimal, for many cases the point of
    AS is that the process is continuing to run, not sleeping, and will
    issue another request shortly.
