[Bug 1309915] Re: foreground app should keep wakelock open until actual suspend happens (aka camera takes ~5 seconds to be responsive after waking phone)

 

This bug was fixed in the package qtmir - 0.4.4+15.04.20150121~rtm-
0ubuntu1

---------------
qtmir (0.4.4+15.04.20150121~rtm-0ubuntu1) 14.09; urgency=medium

  [ Gerry Boland ]
  * Add Wakelock support - ensures device drops to deep-sleep mode only
    when all AppMan suspend tasks have completed (LP: #1309915)

  [ Ricardo Mendoza ]
  * Reduce suspend timeout to half of the previous value because the
    long value was too apparent on fast paced apps, like web games of
    music players; it broke the user experience according to design.

Bug description:
  while apps that you put in the background are properly SIGSTOPed 
  (this is easy to verify with a music streaming website atm (while the browser does not use media-hub it will/should stop playback)).
   An app that is in the foreground will try to play on when the system is suspended (easy to verify with the same method, music plays on but becomes stuttery if the browser was in the foreground. This indicates the system tries to suspend but the running app tries to keep it alive. 

  Unity should send s SIGSTOP/SIGCONT sequence on suspend/resume to the
  app in foreground when the system goes into suspend and resumes.
