- *                               - Removed bug to terminate multiple testbench

- * 24.Mar.2017 - Raj Mohan - Added signal handler for SIGUSR1, to handle an 
- *                           orphan test bench process.
- *                           The test bench will now create a PID file in

- *                           The SIGUSR1 signal serves the same purpose as the 
- *                           "End" signal.
- *                         - Added syslog interface for logging.
