Thanks! This was puzzling me; I had found a few references to Nagle in
searching but it didn't seem to make sense. TCP_CORK appears to be already
used which I thought was in essence manual management of the packet
delays, but I guess not. Yay, linux?
In any case, setting the option correctly makes the server do just what
I was
expecting it to do in the first place.
