I believe both are un-killable. Tie, although Kyuubi may go insane

When did it say that the Kyuubi was unkillable?

I guess I just kinda assumed that from mythology and how none of the Ninjas could beat it with conventional ways, I was thinking you could only kill Kyuubi by killing its host (Naruto). But if thats not the case then Cthulhu wins by default.
