Comment(by katmagic):

 The first request I made to the mapped .exit address through the
 bug3940_022 (43f84c1) successfully connected, but the second failed, with
 Tor logging:

 {{{
 Mar 31 00:00:00.000 [warn] The ".exit" notation is disabled in Tor due to
 security risks. Set AllowDotExit in your torrc to enable it.
 Mar 31 00:00:00.000 [warn] Invalid onion hostname [scrubbed]; rejecting
 }}}

 My torrc was:
 {{{
 SocksPort 19050
 AllowDotExit 0
 MapAddress blah.com check.torproject.org.politkovskaja2.exit
 DataDirectory /tmp/tmp.3HrXkyBcNc
 }}}
