I'm not sure this would work, as the X server runs as root. However,
you may do something along the lines of:

	% su
	# rm -f /core
	# ln -s /dev/null /core

This doesn't prevent your program (X server?) from dumping core,
however, the dump itself goes into a black hole (remember Decus BH: on
RSX?) and won't bother you anymore.
