The DNS test TestSpecialDomainName can hang indefinitely because it sends a DNS request using UDP and waits for a response without specifying a timeout.

The easiest fix would be to add a timeout to the call to exchange so that the test fails quickly with a nice error message if the request gets lost or is ignored. For example:

msg, err := exchange(server, tt.name, tt.qtype, 3 * time.Second)

Ref #13295

Might be nice to not involve the network for these at some point.
