/** Test cases covered in this test code:

1.	Thread create imp destroy then not calling FinalClose() will cause a panic inside the thread( capture this panic)(memory leak)

2.	Thread list implementation then not calling FinalClose() will cause a panic inside the thread(capture this panic)(memory leak).

3.	Thread Create Impl1, Create Impl2, Destroy Impl2, Destory Impl1 then FinalClose() no memory leak.

4.	Thread create Impl1, call FinalClose() 2x, Destroy Impl1 then FinalClose() to show that FinalClose() can be called many times with no unknown consequence.

5.	REComSession::public constructor (without OpenL), called FinalClose () 2x, then Close(), no problem and memory leak.

6.	REComSession::OpenL,call Close() then call FinalClose() to show no memory leak problem.

7.  Test calling REComSession::FinalClose() to show no memory leak, errors, crash problem
