New description:

 In the following control port debug log you'll see I look up the IP
 address of "grepular.com" three times in a row. Look how the octets of the
 IP address in the ADDRMAP responses are reversed in the second and third
 responses:

 {{{
 mike at alfa:~$ telnet localhost 9051
 Trying 127.0.0.1...
 Connected to localhost.
 Escape character is '^]'.
 AUTHENTICATE XXXXX
 250 OK
 SETEVENTS addrmap
 250 OK
 RESOLVE grepular.com
 250 OK
 650 ADDRMAP grepular.com 178.79.145.246 "2012-05-01 01:21:07"
 EXPIRES="2012-05-01 00:21:07"
 RESOLVE grepular.com
 650 ADDRMAP grepular.com 246.145.79.178 "2012-05-01 01:21:07"
 EXPIRES="2012-05-01 00:21:07"
 250 OK
 RESOLVE grepular.com
 650 ADDRMAP grepular.com 246.145.79.178 "2012-05-01 01:21:07"
 EXPIRES="2012-05-01 00:21:07"
 250 OK
 }}}

 If I disconnect and reconnect, they're reversed from the very first
 response. If I restart Tor and try again, then the first response is
 correct, but the subsequent responses are all reversed again. This happens
 for any domain I test. The "tor-resolve" command doesn't display this
 problem. I'm running version "0.2.3.14-alpha"
