Comment (by isis):

 Replying to [comment:3 mikeperry]:
 > Possibly. Do we feel comfortable forbidding these cells completely in
 0.3.4.x? I would prefer to have this branch merged into 0.3.4, since it is
 just a control port field accounting fix.

 > If we're nervous about actually closing the circuit right away in these
 instances, then we should make a different ticket + different patch for
 that change.

 Different ticket and patch please! This one is clearly a bug; disallowing
 0-length data cells entirely seems more contentious, possible requires a
 spec change, and has a higher possibility of breaking things.
