Hello Eric,
These are the only two tests that sometimes fail on my test setup. Whether
or not these tests pass depends on your DNS server. If I e.g. add
"nameserver 8.8.8.8" as the first entry in /etc/resolv.conf then these tests
pass on my setup. I think the reason is that the domain names used by that
test resolve into 127.0.0.x and because some DNS servers filter these
results.
Bart.
You guys have been at this too long. You're failing to document your
assumptions.

Thanks for the patch but some people do not read the documentation
unfortunately. It would make me happier if we could modify the test such
that its outcome does not depend on whether or not an intermediate DNS
server filters out invalid answers.
Bart.
