If you run this software on an Ultrix VAXstation, you may find the
following useful:

- this software is memory hungry and since Xt considers a failure to
  allocate memory FATAL, you can have some fun

- to make Ultrix less likely to make malloc fail you can try the following:

	- sysgen with dmmax set to 64...
	  {also make sure physmem is at least the machine's memory size}
	cd /sys/conf
	add "dmmax	64" to the SYSNAME {config} file
	/etc/config SYSNAME
	cd ../SYSNAME
	make depend
	make

	- make your swap area as big as practical

	- set -DSAFE in the options in xgsh/Makefile
