Sabotaged my ksplash theme to take forever to load, did a qdbus setstage call, once ksplash came up and processed the dbus call, the stage immediately advanced without any obvious sideeffects
It's important that the `setStage` calls are issued without blocking, but `startkde` script does fire-and-forget, KWin, KSMServer, and Plasma issue an `asyncCall`,
