Title:
   FFE Request for Upstart in saucy

Status in “upstart” package in Ubuntu:
  Invalid

Bug description:
  = Overview =

  Bug 1227212 identified that Session Init shutdown for logout takes too
  long in the general case.

  A fix for this issue has now been committed to Upstart upstream.

  = Changes =

  The changes optimise the Session Init quiesce path, making it
  significantly faster to logout.

  = Rationale =

  It would be highly beneficial to make this fix avaiable in Saucy via a
  cherry-pick since it reduces the time to logout of the desktop from
  the current (effectively fixed) 5 seconds to <1 second in the general
  case (*).

  (*) - details of other scenarios are covered on the original MP: see
  https://code.launchpad.net/~jamesodhunt/upstart/bug-1227212/+merge/187844

  = Risk =

  == PID 1 ==

  Perceived risk to PID 1 is: LOW.

  There is really no impact to Upstart running as PID 1 since:

  - PID 1 never quiesces (the code disallows it).
  - The changes for bug 1227212 only affect the quiesce code path.

  == Session Init ==

  Perceived risk to Session Init: LOW.

  The code is accompanied by a set of unit tests which exercise the
  quiesce functionality for Session Inits, both when instructed to exit
  as the result of both:

  - a logout request from the user.
  - a system shutdown.

  Additionally, a new test was added for the changes made for bug
  1227212.

  = Contingency =

  Any contingency would require either further code changes to resolve
  issues or the latest version of upstart containing this fix to be
  removed from the archive.
