	I believe this is not an AIXism but is a BSDism.  The BSD4.3
	csh source I have access to does not support suid either.  This
	is documented, I believe.

	Are you sure this really works?  Suid scripts have never worked
	without "#!".  Your script may run, but it won't run suid.

	(a) /usr/include/sys/limits.h has no effect on process limits (unless
	    you're rebuilding your kernel).  Are you rebuilding your kernel?

	(b) I wasn't aware that max number of procs per user was enforced
	    for root.  If it is, it shouldn't be (IMHO).

	(c) What does ksh have to do with process limits?  Can you give a
	    more specific example of why "chdev -l sys0..." has no effect
	    in ksh (vs sh or csh).
