+ * Test Synopsis:

+ *
+ * Test Method (Validation or Falsification):
+ * - Validation
+ *
+ * Requirements Tested:
+ * - Correct accounting of semaphore and condition variable waiters.
+ *
+ * Features Tested:
+ * - 
+ *
+ * Cases Tested:
+ * - 
+ *
+ * Description:
+ * Attempting to expose race conditions in cond vars, semaphores etc.
+ * - Master attempts to signal slave close to when timeout is due.
+ * - Master and slave do battle continuously until main tells them to stop.
+ * - Afterwards, the CV must be successfully destroyed (will return an
+ * error if there are waiters (including any internal semaphore waiters,
+ * which, if there are, cannot not be real waiters).
+ *
+ * Environment:
+ * - 
+ *
+ * Input:
+ * - None.
+ *
+ * Output:
+ * - File name, Line number, and failed expression on failure.
+ * - No output on success.
+ *
+ * Assumptions:
+ * - 
+ *
+ * Pass Criteria:
+ * - CV is successfully destroyed.
+ *
+ * Fail Criteria:
+ * - CV destroy fails.
