I think the idling feature still needs some work. I created one over the weekend that hasn't idled once, and I've run several tests with sprites that have nothing in them—just `sprite create` and log out, just to see what happens (which unfortunately is nothing, left alone it keeps on running as well.)

I love the idea and most of the execution, I've really enjoyed getting my first sprite configured just the way I want it. It just needs the idling feature to work as advertised before I think I can use it as cost-effectively as it promises.
