I finally looked at the X11R5 server source, and you're absolutely
right, the server is not allocating more than a screen-size of pixmap
for any one window, even a very big one.  Most of that time I was
looking at must have been spent parsing (but then why did `ps' show it
in the server?).  Thanks for correcting my misapprehension on that point.

Yep, as I said earlier, a design decision.
