Doh....that was dumb. FWIW, I'm running 3.5.20, not 3.3

Ok, here is the info from the real trace. First time with #dns_v4_first on
commented out, 2nd time "dns_v4_ first on" is active. Difference is with no
"dns_v4_first on" directive, I get a RR_CONNECT_FAIL 111. When active, I
get a RR_CONNECT_FAIL 101.

#dns_v4_first on   commented out
