    * Choke SSU retransmissions to a peer while there is already a
      retransmission in flight to them.  This currently lets other initial
      transmissions through, since packet loss is often sporadic, but maybe
      this should block initial transmissions as well?
    * Display the retransmission bytes stat on peers.jsp (thanks bar!)
    * Filter QUIT messages in the I2PTunnelIRCClient proxy
