So it is okay for you to waste 30W on seti on running machine on
battery power but you can't waste those remaining 10W...? I guess I'd
either expect seti to stop at battery power...

suspended machine 0.3W
awake machine 10W
machine running seti 40W

...? (thinkpad x60).

Ok... for something less computing intensive, it might make
sense... but I guess those examples are less widespread than you
expect.

I'd expect desktop environment to stop wasting cycles/electrons on
that when user can't see the screen.
