 // PepperViewProxy is used to invoke PepperView object on pepper thread. It
 // has the same interface as PepperView. When a method calls is received on
 // any chromoting threads it delegates the method call to pepper thread.
 // It also provide a detach mechanism so that when PepperView object is
 // destroyed PepperViewProxy will not call it anymore. This is important in
 // providing a safe shutdown of ChromotingInstance and PepperView.
