Comment (by arma):

 Looks better yes. I wonder if there are other edge cases.

 As for the attack you describe, yes. I think that used to be possible too
 by answering with a created-fast and then just dropping any extend or
 begindir cells?

 I guess another option here is what you were heading toward originally: we
 dump the guard if it ever can't process one of our create requests. That
 seems a poor plan though, especially in light of the current circuit
 create load?
