i have a few users logged in to a machine i'd really love to reboot
(say, because i'm adding an option to cpurc).  in a unix world i'd use
"wall" to tell them "reboot forthcoming in 5, 4, 3, 2, 1..." but in
plan 9 i can't do anything short of forcing them to listen to some
"announcement" file descriptor from /src...

how could i do something similar in Plan 9 with minimal effort?  i
know at some point it was customary to warn users by shouting across
the unix room, but some of the users here are rather far away...
