    The called object for closing must post the closing events immediately
    and before any internal cancel operations will be started.
    If a listener disagree with that it should throw a CloseVetoException
    and called function XCloseable::close() must be broken immediately.
    It's not allowed to catch it inside the close() request.
    If no listener nor internal processes hinder the object on closing
    all listeners get a notification about real closing.
