Verify that the resolver selects authoritative servers in increasing SRTT order. Four servers are configured with increasing response delays. 100 queries are sent, expecting most to go to the fastest server (ns2). Then ns2 stops responding, another 100 queries are sent and should go to ns3 (the next fastest), and so on through ns4 and ns5. Each query uses a unique name to avoid cache hits.
