The behavior is different in a telnet session as is executing ssh server 'find / -print | dd obs=1'. Telnet pauses but not as long, the ssh command saturates my fractional T. What I am seeing may not be related to the issues Greg brought up at all. But it does seem odd to me that a window of data is queued on the server, the server has recevied the ack for the last byte it sent, but the server does not start sending until the client acks the same byte again with a data bearing segment. Don't know what the data bearing segment contains, ssh stuff maybe.
