I can't comment on the unbound/Tor specifics, but note that it's totally 
possible to get bind into a state where it won't respond at all in the 
cited time windows, if upstream connectivity is broken. I've seen this 
on a number of occasions.

Am I correct in understanding that the Tor/eventdns code is, 
effectively, self-DoS'ing by marking all of its nameservers dead for 
increasingly long backoff times?
