  37 # On windows tests if it returns -1.0 The verification is done
  38 # by the GetSystemLoadAverage class.  By default it takes no
  39 # input argument which verifies the system load average with
  40 # /usr/bin/uptime command. Or specify "-1.0" as the input argument
  41 # indicatiing that the platform doesn't support the system load average.
