> If a given InvokerCallbackHandler is passed to Client.addListener() multiple times, a new CallbackPoller will be created each time, although only the first one leads to the registration of a new ServerInvokerCallbackHandler with ServerInvoker on the server side. 
> The semantics, according to Chapter 5 of the Remoting guide, should be
> If there is no callback Connector, which is the case for pull callbacks and simulated push callbacks (see Section Registering callback handlers), then the callback connection is identified by the combination of the Client on which addListener() was invoked and the InvokerCallbackHandler. It follows that if an InvokerCallbackHandler is registered twice with the same Client for pull or simulated push callbacks, only a single callback connection is created. That is, the second call has no effect.
> So only one CallbackPoller should be created per (Client, InvokerCallbackHandler) pair.
