+ * Description:
+ * - 
+ *
+ * Test Method (validation or falsification):
+ * - validation
+ *
+ * Requirements Tested:
+ * - keys are created for each existing thread including the main thread
+ * - keys are created for newly created threads
+ * - keys are thread specific
+ * - destroy routine is called on each thread exit including the main thread
+ *
+ * Features Tested:
+ * - 
+ *
+ * Cases Tested:
+ * - 
+ *
+ * Environment:
+ * - 
+ *
+ * Input:
+ * - none
+ *
+ * Output:
+ * - text to stdout
+ *
+ * Assumptions:
+ * - already validated:     pthread_create()
+ *                          pthread_once()
+ * - main thread also has a POSIX thread identity
+ *
+ * Pass Criteria:
+ * - stdout matches file reference/tsd1.out
+ *
+ * Fail Criteria:
+ * - fails to match file reference/tsd1.out
+ * - output identifies failed component
