* As of 1.1, the resolver system is seperated out from BufferedSocket, so we must do this
* resolver step first ourselves if we need it. This is totally nonblocking, and will
* callback to OnLookupComplete or OnError when completed. Once it has completed we
* will have an IP address which we can then use to continue our connection.
