- * Test Description:
- *  The process does a fork:
- *	1) By the value returned by child's alarm(0), check whether child
- *	   process cleared the previously specified alarm request or not.
- *	2) By the value returned by parent's alarm(0), check whether parent
- *	   process cleared the previously specified alarm request or not.
+ * Verify that alarms created by alarm() are not inherited by children
+ * created via fork.
