I noticed that this app need not depend on base at all. Darin mentioned it might
be good to have a Mojo app that didn't depend on any Chrome code at all. It
could be this one, though if we want to have something that works with our other
base-reliant services, we would have to write one that does.

Do we want to set running_ to false at some point?
