Changes (by mikeperry):

 * milestone:  Tor: 0.4.1.x-final => Tor: unspecified


Comment:

 FWIW, these protocol errors do not impact vanguard's ability to detect
 that cells were dropped. Also, since Tor is already closing the circuit
 with torprotocol itself, these don't represent a very large side channel
 issue.

 I think taking this out of 0.4.1 and maybe even lowering priority is OK. I
 will just do the 0.4.1 bit now.
