Code review comment for lp:~gerboland/qtmir/fix-lifecycle-exempt-keeps-wakelock

Hey, just wanted to check the following usecase is not broken with this code...

1) Open Music-App
2) Start playing a set of songs
3) Switch to another application
4) Suspend/lock the phone
5) Wait until the track ends, the next track should start playing

The main reason left that we have the lifecycle exception is to be able to tell media-hub what the next track is to play, this should be fixed once background-playlists are implemented in media-hub.
