 Lettuce failure on CentOS 5.8 with python 3.3.0. This does not happen
 every time, but I saw it only one time out of six runs.

 Scenario: ACL
         # features/ddns_system.feature:89

 ...

     A query for new1.example.org should have rcode NXDOMAIN
 # features/terrain/querying.py:204

 ...

     AssertionError: Expected: NXDOMAIN, got NO_ANSWER

 Here is some stderr output that may be related (but I am not sure):
