* Added a watchdog timer to do some baseline liveliness checking to help
      debug some odd errors.
    * Added a pair of summary stats for bandwidth usage, allowing easy export
      with the other stats ("bw.sendBps" and "bw.receiveBps")
    * Trimmed another memory allocation on message reception.
