Yup, SSH must be using TCP_NODELAY interactively.  I can't see how else 
that would work.  And OpenSSH docs say it uses TCP_NODELAY for X 
forwarding, so that makes sense.
Which means that our "intelligent" update on terminals, which does 
potentially many writes may produce as many packets.  Which may be a 
problem sometimes :-).
It wouldn't be hard to buffer the writes until the update is done, I 
think.  But is it worth it as an option?  Don't know.
