It seems that forwarding of X _is_ working.  However, it is operating very
slowly, and I'm not yet sure why.

What I can see is that for some reason X protocol packets are being sent
over my dial-up Internet connection at the sametime as between the two
(Ethernet-connected) machines that I'm using.  This seems to only happen
with an X client running on one machine (with the modem) and the X server
running on the other machine.  This greatly slows down all display
activity (opening a window, as well as refreshing contents, as of an
xterm).

Because I happened to be downloading a large .tar.gz file for pkgsrc, the
process was running even more slowly, and appeared to freeze without even
opening a window.  Since I didn't know that it was using the modem (and
still don't know WHY it was using the modem), I assumed that X forwarding
was broken.

Once the pkgsrc file finishes transferring, I'll try using xauth between
the two machines to see whether the behavior is just under an
ssh-forwarded session.  The problem may be a network mis-configuration on
my part.  However, most stuff seems to work correctly so I can't see why
just X, or just X-under-ssh, should be misbehaving.

(Running X purely on the local machine works exactly as one would expect.)
