    This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

    This API is available on Firefox OS for internal applications only.

    Each call to SettingsManager.createLock() create a new SettingsLock object.

    All SettingsLock objects are kept in a queue of active locks. When a SettingsLock object is created it's placed at the end of the queue. Calls to get/set places a request against the lock on which it's called. Requests run asynchronously and in the order they are placed against a lock. When the last request for a lock is run, and  the success/error event against it has been fired, the lock is removed from the queue and the next lock start to be processed.


    Indicates if the lock is no longer the active lock (true) or if it's still the active lock (false)
