Comment 27 for bug 1516696

rild holds a wakelock for only 200ms so its quite possible the phone suspends while we are waiting on that timer. Also, QTimer must not use hardware wakeup events or things would work. We need to figure out where to put a wakelock request, repowerd provides an interface for this. It wold also be good to remove that timer and find a better way to handle when messaging app is open.

See comment #25 which is a similar issue with clock alarms in indicator-datetime, although it has logic to keep the device awake which is clearly not working.
