62 *	1.) pause(2) returns...(See Description)
63 *
64 *    INPUT SPECIFICATIONS
65 *	The standard options for system call tests are accepted.
66 *	(See the parse_opts(3) man page).

69 *
70 *    DURATION
71 *	Terminates - with frequency and infinite modes.
72 *
73 *    SIGNALS
74 *	Uses SIGUSR1 to pause before test if option set.
75 *	(See the parse_opts(3) man page).

88 *
89 *    DETAILED DESCRIPTION
90 *	This is a Phase I test for the pause(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 *	pause(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 *	  Print errno log and/or timing stats if options given
108 *
