 Somewhat related to discussion on #8093 -- people are still setting up
 exit nodes to use OpenDNS or Google DNS.  Is that really a safe idea?
 That makes it distressingly easy for these DNS services (or anybody
 watching them) to get timing information on user DNS requests.

 Furthermore, the default OpenDNS configuration blocks some stuff.  If we
 don't warn about OpenDNS in general, maybe we should warn when configuring
 an OpenDNS server in a way that hasn't disabled blocking.
