> AuthenticationToken objects are Destroyable. However, this cannot be 
> exercised properly in the client code, because the Connector immediately 
> serializes the credentials and stores them as long as the Connector lives.
> It should be possible to destroy a token after creating a Connector, and 
> thereby forcing any further RPC calls initiated by that Connector to fail to 
> authenticate. This means that serialization on the client side to a 
> TCredentials object needs to occur just before the RPC call.
