This should be obvious to everyone here but just in case, there's also
a huge difference between hammering the control plane of every router
along the path due to TTL expiration (mtr) and trying to smoke out
intermittent performance problems between end points with a few
hundred packets/second of various sizes of icmp or udp *between those
end points*.  Folks should expect the former to be rate limited - a
reasonable control plane policing policy is not optional these days.
