Hmm seems like I need to sleep between calling original resource reports
and TwillController.restartAllInstances because just checking existing resource
reports could return the same containers.
But I could eliminate the first sleep.

> Once an application is running, it would be good to be able to stop, start,
> and restart a specific runnable of the application without affecting other
> runnables.
> For example, I may be running multiple services in a single application, with
> each service as a different runnable. One of my services gets into an invalid
> state. I now want to restart just that runnable and not the other ones that
> are running properly.
