    What's complicated about the scheduler? I see simple/elegant when I
    look in there. Interaction with the user is complex, but interactive
    feel is a nebulous thing not restricted to this scheduler.

    I really don't think this patch adds complexity, quite the opposite
    actually. It just does a small bit of tweaking to the scheduler's weak
    spot, and adds a dirt simple barrier against starvation. IMO, this
    scheduler is not only quite simple, it's one weakness is generally
    wonderful for throughput. It's just that it's sometimes a bit _too_
    wonderful ;-)
