Code review comment for lp:~gerboland/unity-2d/keymonitor-shutdown-fixes

No unfortunately it doesn't help with logout-time, I suspect the communication between gnome-session and Launcher at logout is incomplete.

But without this patch QCoreApplication::quit() does not quit the Launcher as the QtConcurrent thread does not halt. So this is a step in right direction, as otherwise the process needs to be killed.

This also keeps code consistency with GEIS gesture handler.
