This command sends a
bus error signal to the
process. This
signal name doesn't correspond to
one signal number in particular, it depends on the
system. Usually the
system sends these
as necessary, so you won't need to use it often.
If you read it literally, it seems to say "kill the process by hitting it with a bus". Maybe leave it in the path of the system bus, sort of like tying a lady to the train tracks like they did in cartoons or bad movies.
