Thanks. So is the idiomatic approach for this with something like the FTPClient to subclass it and override connectionLost? FTPClientBasic clears up queued commands when this happens (which I assume I still want it to do).
To me it seems a little overbearing to have to subclass the ftpclient just to get a tcp connection lost event (which seem like an event most users would be interested in).
