message: Explicitly call log::set_max_level (Closes:
  For some reason, log 0.4 requires that we explicitly set the log level
  with log::set_max_level or it defaults to Off.  The documentation
  isn't clear but suggests we must do this in addition to doing the
  filtration ourselves in the Log impl.
