I am *not* sure. As I said, the last thing was shotwell photo
editing. It might be some io while loading the photos, but
after that they are in the cache, and the only thing is done is
lots of displaying.

Anyway, that is my idea. I think I don't need google. A simple
	svn up
on my 15Gb svn repository creates enough io. And doing some git pull
or so on same sized repositories in parallel brings anyway the
laptop to its knees (actually, badly to its knees).

Best wishes
