* Rather than profile individual tunnels for throughput over their
      lifetime, do so at 1 minute intervals (allowing less frequently active
      tunnels to be more fairly measured).
    * Run the live tunnel load test across two tunnels at a time, by default.
      The load test runs for a random period from 90s to the tunnel lifetime,
      self paced.  This should help gathering data for profiling peers that
      are in exploratory tunnels.

    * Calculate the overall peer throughput across the 3 fastest one minute
      tunnel throughput values, rather than the single fastest throughput.
    * Degrade the profiled throughput data over time (cutting the profiled
      peaks in half once a day, on average)
    * Enable yet another new speed calculation for profiling peers, using the
      peak throughput from individual tunnels that a peer is participating in,
      rather than across all tunnels they are participating in.  This helps
      gather a fairer peer throughput measurement, since it won't allow a slow
      high capacity peer seem to have a higher throughput (pushing a little
      data across many tunnels at once, as opposed to lots of data across a
      single tunnel).  This degrades over time like the other.
    * Add basic OS/2 support to the jbigi code (though we do not bundle a
      precompiled OS/2 library)
