    Description

      Tasks are basically on two levels, guaranteed and speculative, with speculative being the default. As long as noone uses the new flag, the tasks behave the same.
      All the tasks that do have the flag also behave the same with regard to each other.
      The difference is that a guaranteed task is always higher priority, and preempts, a speculative task.
