I've checked a "real" case: DNSSRV-located DSAs, one responding and one
not.  Things seem to work as expected, no cores and valgrind shows no
issue.  In any case, I have committed a few modifications to HEAD code
(plugs a potential leak).  Please test and either provide more details
about the core or more details about the configuration.
