DNS TXT support
I've tweaked it a little bit, still seems to work ...
I'd like to add a test for this but I'n not quite sure how to do that.
We'd have to hardcode a destination server that then'd be contacted
each time the test-suite runs.
The trailing dot on "localhost." circumvents use of /etc/hosts in
some environments (I saw it on FreeBSD 9.0-RELEASE-p3) and so emits
an actual DNS query. When running the test suite, that would be
hundreds of useless queries.
