*
* Description:
* -
*
* Environment:
* - This test is implementation specific
* because it uses knowledge of internals that should be
* opaque to an application.
*
* Input:
* - None.
*
* Output:
* - File name, Line number, and failed expression on failure.
* - analysis output on success.
*
* Assumptions:
* -
*
* Pass Criteria:
* - unique sequence numbers are generated for every new thread.

* Fail Criteria:
* -
