'w' for Iris 4D

[Rayan Zachariassen]

neat.cs.toronto.edu:~ftp/pub/sgi/w.tar.Z contains w.c and etc/lavd.c, the
latter a daemon which puts the load average in shared mem segment for the
benefit of w.c.  This is for 3.1, and should work under 3.2 although it seems
avenrun will be available in 3.2.  Hmm, perhaps the kernel should maintain the
shmem segment.  This stuff is PD as a subtle encouragement for SGI to provide
a 'w' with their releases. (hint, wink, nudge, ...)
