Because Interceptors disable COM garbage collection to improve performance, they never receive Release calls from remote clients. If the object can be shut down while clients still hold a reference, this function can be used to force COM to disconnect all remote connections (using CoDisconnectObject) and thus release the associated references to the Interceptor, its target and any objects associated with the HandlerProvider. A HandlerProvider::DisconnectHandlerRemotes method also had to be added to allow HandlerProviders to disconnect clients for their own objects.
