   The N^2 effect isn't so bad when you've got

   idea was to make rwhod write into /usr/lib/rwho instead of
   /usr/spool/rwho.

Better, run an rwhod which doesn't broadcast at all, but rather [a]
NFS-mount /usr/spool/rwho from a single server, and then [b] just
scribbles /usr/spool/rwho/its-own-name.  Poof, no more broadcasts at
all.
