   * 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.
