Koalemos example daemon

I'm pretty proud of the name: http://en.wikipedia.org/wiki/Koalemos

Running `sleep 30` and killing it definitely makes it easy to find bugs in shutdown and such.
(That being said this does raise the interesting question of whether we need to have a `Stop` vs. `Abort` or something where `Abort` would send SIGKILL. I think the answer for now is "no", but I'm open to ideas.)
