We have users who refuse to run number-crunching programs suitably
"nice"d on our server, often resulting in several users' workstations
being locked up waiting for access.

Is there any way to have the user's login run at a suitable nice value?
I heard that some login's look for a "pri=n" string in the GCOS field.
However, on our Sun (SunOS4.1) this doesn't seem to work (i.e.,
GCOS is :pri=10,Name,office,phone:).

I've even tried to run a C program which nices itself and then execs
/bin/csh ...

	#ifndef NICEVAL
	#define NICEVAL 10
	#endif
	main(argc, argv)
	int argc;
	char *argv[];
	{
	  setpriority(0, getpid(), NICEVAL);
	  execl("/bin/csh", "-csh", (char *)0);
	}

but this doesn't always seem to work (can't remember why).  Am I doing
something wrong here?
