In practice, didn't we want most tasks to behave like RT?
(for interactivity purposes) -- I recall hearing that's basically
what good interactivity meant; short reponse times to events.

So then, taking await batch/bacground data-munching jobs, we fold 
back to needing a good RT-like behaviour. And then we can reach > 140.
