  89  *    DETAILED DESCRIPTION
  90  *      This is a Phase I test for the fcntl(2) system call.  It is intended
  91  *      to provide a limited exposure of the system call, for now.  It
  92  *      should/will be extended when full functional tests are written for
  93  *      fcntl(2).
  94  *
  95  *      Setup:
  96  *        Setup signal handling.
  97  *        Pause for SIGUSR1 if option specified.
  98  *
  99  *      Test:
 100  *       Loop if the proper options are given.
 101  *        Execute system call
 102  *        Check return code, if system call failed (return=-1)
 103  *              Log the errno and Issue a FAIL message.
 104  *        Otherwise, Issue a PASS message.
 105  *
 106  *      Cleanup:
 107  *        close file
 108  *        remove temp directory
 109  *
