 Right now, AFAICT, our DNS testing code only looks for hijacking: the case
 where all names (or just NXDOMAIN names) get redirected to a small set of
 IPs.  But it doesn't actually check for cases where all the names we
 lookup get timeouts or fail.  We should probably detect that too, and also
 treat that as meaning that our DNS is broken.
