Heh.

I think there's just some bad network in the middle here.  No
packet loss, though, but the congestion window nearly never opens
up above 64KB.  Then there's the application-window in ssh
itself, but we have the HPN additions on both client and server,
so it *should* be able to scale that higher than 64KB(?)
