Comment(by cypherpunks):

 > and the circID case too

 Then please clarify torspec too:

 > The CircID field determines which circuit, if any, the cell is
 associated with.

 > The CircID for a CREATE cell is an arbitrarily chosen 2-byte integer

 It need clarify that no zero for circuit allowed, only for "control" cells
 (from handshake).
