No, the server just registers that key as a key that will push all the data.
It would be more efficient than anything that the Nagle algorithm could
produce AND give the best responsiveness.
BTW All correctly written terminal programs will push all data out and
defeat the Nagle algorithm anyway.

Of course, as I specified in my original message!
