 // The tests in this file attempt to verify the following through simulation:
 // a) That a server experiencing overload will actually benefit from the
 //    anti-DDoS throttling logic, i.e. that its traffic spike will subside
 //    and be distributed over a longer period of time;
 // b) That "well-behaved" clients of a server under DDoS attack actually
 //    benefit from the anti-DDoS throttling logic; and
 // c) That the approximate increase in "perceived downtime" introduced by
 //    anti-DDoS throttling for various different actual downtimes is what
 //    we expect it to be.
