Using a 1/10th of a second interval is rather anti-social. I know we rate-limit ICMP traffic down, and such a short interval would be detected as attack traffic, and treated as such.

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. -r
