Comment(by arma):

 Hm. Running it on moria1 with protocolwarnings 1, I see quite a few
 {{{
 Jul 01 05:37:54.000 [warn] Bug/attack: unexpected sendme cell from client.
 Closing circ.
 Jul 01 05:37:54.000 [warn] connection_edge_process_relay_cell (away from
 origin) failed.
 Jul 01 05:37:54.000 [warn] circuit_receive_relay_cell (forward) failed.
 Closing.
 }}}

 I wonder if these are people performing the exploit, or people otherwise
 doing something unexpected.
