- Limit buffer size; block and wakeup writer when full
      - Limit errors written to system log
      - Add method to force a log below the current level

      - Fix bug causing PacketPusher to loop quickly instead of sleeping
      - Fix udp.sendCycleTime and sendCycleTimeSlow stats
      - Fix speed values on peers.jsp
      - Try to fix rare NPE (ticket 298)

      - Use System locale and time zone for default date/time format,
        so it matches the wrapper log time (we can't set the wrapper log time zone).
        (existing installs must remove logger.dateFormat line
         in logger.config to get system default format)
      - Force RuntimeExceptions to CRIT level
      - Don't have log() count buffer size

             so each sub-build.xml is only executed once (true DAG)
