  Modified files:
    test/sysperf         pipe2.c 
  Revamp the PIPE test a bit.  Use a calibration loop to make the test always
  run for a consistent period of time (around 6 seconds) no matter what the
  specified block size is.  Allow a third 'label' argument to be specified
  and reformat the MB/sec output to include the label and block size
  to make it easier to pick off results for gnuplot.  Finally, use mmap()
  instead of malloc() to create a cache-friendly read and write buffer to
  reduce noise in the performance results.
