> - * 	  Setup signal handling.
> - *	  Pause for SIGUSR1 if option specified.
> - *
> - * 	Test:
> - *	 Loop if the proper options are given.
> - * 	  Execute system call
> - *	  Check return code, if system call failed (return=-1)
> - *		Log the errno and Issue a FAIL message.
> - *	  Otherwise, Issue a PASS message.
> - *
> - * 	Cleanup:
> - * 	  Print errno log and/or timing stats if options given
