Makes absolutely no perceivable difference. However, there is an enormous
amount of network traffic going by, as I can see by the flashing light on my
NIC. This happens any time a new emacs mode (library) loads on the remote
machine. What in the world could it be accessing on my local machine? All
that handshaking, just as emacs starts up?!?

I heard some rumour that you can work around this with .Xauthority, but I'm
tired of diddling around with things I don't really understand, and I still
can't understand why there should be any difference between emacs -nw and
emacs when it comes to loading libraries.
