I got this same problem on a DECstation 5000, running either the X.V11R4
Xcfbpmax or the DEC-supplied one. The problem arose the first time I
popped up some menu. With tvtwm the problem was even worse.

It's a problem with save-unders, it can be worked around by starting the
X server with the -su (no save-unders) flag. This is either in the xdm
server configuration files or (if you're using xdm) or in /etc/ttys.

After that, the X server's growth is not significant (ie. doesn't grow
to 20M as soon as I do anything).
