lat_pipe  uses  two  processes  communicating  through  a Unix pipe to measure interprocess communication
       latencies.  The benchmark passes a token back and forth between the two processes (this sort of benchmark
       is frequently referred to as a ``hot potato'' benchmark).  No other work is done in the processes.

       The reported time is in microseconds per round trip and  includes  the  total  time,  i.e.,  the  context
       switching overhead is includeded.  Output format is like so
