> When the region is opened, we register the region to the ConfigurationManager
> as a ConfigurationObserver object.However, when the region is closed, we
> don't deregister the region as a ConfigurationObserver object from the
> ConfigurationManager correspondingly. It's not a bug for now cos we can
> update the conf whenever the region is open or not.But it is bug-prone, and
> we should remove it from the ConfigureManager object when the region is
> closed.
