I'm not sure this is the API we want for application lifetime. I'm not sure we
want any explicit "you should shutdown" event. We may be better served only
providing "suspend/resume" events. If suspended, you might be killed. However, I
guess the issue is that we need some kind of explicit "now you are killed" event
to handle the case of single process mode or multiple apps loaded into the same
process? Hmm...

If the primordial app exits and we want to quit the shell, we'll want to kill
other apps...
