Bug description:
  I've noticed the shutdown and reboot in oneiric is slower than in
  natty. This is reproducible on different machines with fresh
  installations.

  Disabling plymouth and vt.handoff=7 I can see that some processes are not closed:
  * Asking all remaining processes to terminate... [OK]
  * Killing all remaining processes... [fail]

  Killing network-manager at runlevel6, after the dbus shutdown signal,
  makes the shutdown and restart really faster (I'd say 5/10sec on low
  end machines like netbooks)
