 > Ok reading you code, I think that the main problem is that you are
 waiting for the ACK before continuing to send data, while openSSH just
 send stuff as fast as it can until he fills the queue, then check for ACK
 when the sent queue is filled ...

 I don't see how the patch attached changes this behaviour. It will still
 toggle between writing and reading the status.
