The problem is that non-foreground apps are SIGSTOPed, meaning that they
won't find out about unity8 dying until such time that they get resumed
again. Which will not happen if it crashed... So yeah, they still do get
orphaned.

I'm thinking that the whole session should be brought down and
restarted, which would cause upstart to SIGKILL all the suspended apps.
Otherwise we'd need to try and tell upstart to kill them one by one...
but we're in the process of crashing, so it's not like this would ever
be reliable, would it?

  Applications are orphaned when unity8 crashes

Bug description:
  For some reason Unity8 crashed on me. The applications I had open are
  now orphaned. They're still running but you can't get to it as it no
  longer shows up under the recent applications. In addition if I
  attempt to start the app, it fails to run or come back from orphaned
  state, so I have to restart.

  My unity process where Unity8 died an hour or two back.
