    Scheduling contexts do sound useful. They're easily defeated though, as
    evolution mail demonstrates to me every time it's GUI hangs and I see
    that a nice 19 find is running, eating very little CPU, but effectively
    DoSing evolution nonetheless (journal). I wonder how often people who
    tried to distribute CPU would likewise be stymied by other resources.
