 // constructor will be called with a true success value after the Sync server
 // has flipped the acknowledgement flag for the setting. If another client
 // changes the value in the mean time, the callback will be run with a false
 // success value. If the object is destroyed before that, the callback will not
 // be run. Note that any changes made to the setting will not be undone when
 // destroying the object, even if the update was not successful or was canceled.
