[Bug 1304257] Re: [enhancement] There should be a quit signal sent to sessions instead of killing them directly

[Ted Gould]

Currently upstart to stop a job sends SIGTERM and then waits 5 seconds
and sends SIGKILL. I think the issue is that we need to send SIGCONT
first for it to get the TERM.

Bug description:
  The task manager currently kills (upstart-stops) the apps upon the
  user requesting it to stop. It should send a quit signal instead (and
  SIGCONT it first, if stopped), so that the app can shut down
  gracefully.

  A method to forcefully quit the app is needed, too, if it's not
  responding (or maybe even just timeout-based).
