	There is a "memory leak" in the 4.0 and 4.1 servers (RISC/VAX)
that apparently stems from save-unders and some interaction with the
memory allocator. This will be fixed in 4.2.

	A work-around is to start the server without save-unders, as
"Xcfb -su" in /etc/ttys. Running without save-unders isn't a performance hit
unless you're doing complex pictures.
