Write a small program that calls setrlimit() to set the maximum
core dump size to zero and then calls execv() to invoke the X server.

Cause this program to be invoked instead of X, either by changing the
invocation by the OS (I forget where this is; it used to be in /etc/ttys)
or by renaming X to X.real and this little program to X.

I used this approach to cause my system's news software to run with
an adequate maximum file size (ulimit).  It works fine here (on an
RT AIX system, not ULTRIX).
