    Compare speed of writing data to a remote UDP listener using 2 different methods:
        * Write to stdout/stderr and pipe to remote listener using netcat
        * Write directly to the remote listener
    
    Start in another shell a listening UDP server which writes data to /dev/null:
        
        $ nc -klu localhost 10000 > /dev/null
        
    Start this script by redirecting STDERR to a nc process:
    
        $ python compare_stdout_socket.py 2> >(nc -w1 -u localhost 10000)

| test_1   | Write to STDERR so we can redirect this output and keep the TestLap summary on STDOUT. | OK     | 39.4371290207 |
