* Reenable the probabalistic drop on the TCP queues to deal with good old
      fashioned bandwidth limiting.  However, by default the probability is
      rigged to reserve 0% of the queue free - meaning we just aggressively
      fail messages in the queue if we're transferring too slowly.  That
      reservation factor can be increased with 'tcp.queueFreeFactor=0.25'
      (or whatever) and the drop code can be disabled with the parameter
      'tcp.dropProbabalistically=false'.
    * Still penalize a peer on tunnel failure, but don't immediately drop
      their capacity to 0.
    * More aggressively ACK duplicates
    * Randomize the timestamper period
    * Display the clock skew on the connection logs when a peer sends it.
    * Allow the timestamper to fix skews of up to 10 minutes
    * Logging
