/**
 * Interface to allow a component to declare that it is stateful (client-specific state or other) 
 * and can only be restarted (without surprising effects for its clients) 
 * if its state is handled by the container using the methods of this interface.
 * <p>
 * About references to components and callback objects: 
 * Baci monitors will be stored and reconnected automatically by the container.
 * Component references should be stored not as Corba IORs, but as qualified names 
 * which allow to request the real reference again from the manager. 
 * We will have to disucss how dependencies among a group of restarted/restored components can be handled this way.
 * Also for restarting a component, the manager should not release the components that this component is a client of.
 * Perhaps we should have a separate method to get and set component references or other Corba references.
