// we're not stopping the keep-alive timer and disposing the session here
//
// we could do this but there would still be side effects as concrete
// implementations may still hang on to the original session
//
// therefore it would be better to actually invoke the Disconnect method
// (and then the Dispose on the session) but even that would have side effects
// eg. it would remove all forwarded ports from SshClient
//
// I think we should modify our concrete clients to better deal with a
// disconnect. In case of SshClient this would mean not removing the
// forwarded ports on disconnect (but only on dispose ?) and link a
// forwarded port with a client instead of with a session
//
// To be discussed with Oleg (or whoever is interested)
