* Upstart stupidly doesn't kill post-start scripts if we do "stop

JOB", but it does kill the job's main process.  So if the post-start
  script if waiting for the job's main process to reach some state, it
  may hang forever.  Thus, the post-start script should monitor
  whether its job has been requested to stop and exit in that case.
