Comment (by jinmei):

 Replying to [comment:7 vorner]:
 > No, all the queries are local now, because the address of l root server
 is hardcoded (I'm sure about it, my provider blocks all DNS traffic except
 to his own servers and the test passed here). This'll not be always the
 case, but it works for now and we'll need some more tests when we do more
 on the resolver.

 But doesn't that necessarily mean it never sends queries outside?  Or
 is that what you mean by "not always the case"?
 (Besides, this sounds like the resolver returns records from its
 "hints" if all external servers are unreachable.  I suspect it's the
 wrong behavior - at least should be incompatible with BIND 9.  But of
 course that's a different matter).

 My point is that (IMO) it should never send queries outside the test
 node, especially should not spam a public root server.  It's not
 whether the test succeeds when the node is disconnected (which is
 itself important though).

 Hmm, lettuce seems to be completely broken in my environment now, so I
 cannot test it myself.

 And btw, I noticed one minor editorial nit, so I fixed it.
