  | I think the issue is related to session suspend/resume in MinaHandler.

  | We can suspendRead the session when we receive a message.
  | The resumeRead can occur when we sent a message.

  | But we have cases where the server receives a lot of one-way messages (potentially suspending the session) and do not send a message (thus never resuming the session).
  | E.g. the client acknowledge a lot of messages and close the session.
  | At one point, when receiving an ack, the server's MINA Handler will suspendRead the session. Since the server does not send any messages, the session will not be resumeRead and the CLOSE message will not be handled.
  | 
  | We can't assume that we have as much messages received as message sent (and vice versa). It seems we need to rethink our algorithm to take into account these cases.
