The branch does not have any changes with respect to detecting rate
limiting. The only change is how it responds when it is detected. I
don't have any big samples of rate limiting and congestion.

Measuring changes in RTT is just one of the ways we considered to detect
rate limiting. See http://seclists.org/nmap-dev/2009/q1/0049.html.

All my scan results from different rate limiting scenarios are at
