 * keywords:  tor-relay resolv.conf  dns => tor-relay resolv.conf  dns dos-
     maybe
 * milestone:  Tor: unspecified => Tor: 0.3.3.x-final


Comment:

 This could be a potential DoS risk if DNS goes down for an exit, and it is
 HUP'ed while DNS its down. It would be nice to get it fixed in the next
 year or so.

 Damian, can you confirm that your system is non-macOS?
