     49  *    SIGNALS

     65  *    DETAILED DESCRIPTION
     66  *	This is a Phase I test for the fcntl(2) system call.  It is intended
     67  *	to provide a limited exposure of the system call, for now.  It
     68  *	should/will be extended when full functional tests are written for
     69  *	fcntl(2).
     70  *
     71  *	Setup:
     72  *	  Setup signal handling.
     73  *	  Pause for SIGUSR1 if option specified.
     74  *
     75  *	Test:
     76  *	 Loop if the proper options are given.
     77  *	  Execute system call
     78  *	  Check return code, if system call failed (return=-1)
     79  *		Log the errno and Issue a FAIL message.
     80  *	  Otherwise, Issue a PASS message.
     81  *
     82  *	Cleanup:
     83  *	  Print errno log and/or timing stats if options given
     84  *
