Comment (by cypherpunks):

 > There's a corner-case here: what to do if we get a CREATE cell for a
 circuit on which we have a pending DESTROY.

 Dropping of cell is correct behavior. The one circuit is the one create
 cell and the one destroy cell that was received or sent. It's sad if
 another party can to get any answer for such corner cases but broken logic
 for code where we sends several destroy cells is worse solution.
