 Unplug your ethernet (but leave the interface up), and then run tor's
 'make test'. It will stall at "pt/parsing" for a minute or so.

 It has to do with these two tests in src/test/test_pt.c:
 {{{
   /* wrong addrport */
   strcpy(line,"CMETHOD trebuchet socks4 abcd");
   test_assert(parse_cmethod_line(line, mp) < 0);
 [...]
   /* wrong addr type */
   strcpy(line,"SMETHOD trebuchet abcd");
   test_assert(parse_smethod_line(line, mp) < 0);
 }}}

 parse_cmethod_line() calls tor_addr_port_lookup() which calls
 tor_addr_lookup() which triggers the dns lookup.

 I haven't explored whether having my resolver *answer* the dns query can
 change the behavior of the unit tests.
