+ * Test Synopsis:
+ * - Test timeout of multiple waits on a CV with some signaled.
+ *
+ * Test Method (Validation or Falsification):
+ * - Validation
+ *
+ * Requirements Tested:
+ * -
+ *
+ * Features Tested:
+ * -
+ *
+ * Cases Tested:
+ * -
+ *
+ * Description:
+ * - Because some CVs are never signaled, we expect their waits to time out.
+ * Some are signaled, the rest time out. Pthread_cond_destroy() will fail
+ * unless all are accounted for, either signaled or timedout.
+ *
+ * Environment:
+ * -
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * -
+ *
+ * Pass Criteria:
+ * - pthread_cond_timedwait returns ETIMEDOUT.
+ * - Process returns zero exit status.
+ *
+ * Fail Criteria:
+ * - pthread_cond_timedwait does not return ETIMEDOUT.
+ * - Process returns non-zero exit status.
