* Add MxSemphore + MxThread and the two implementations I could find of MxThread (consumers extend it and override the Run method). * Implement a function in MxDiskStreamProvider which uses thread and semaphore to confirm correct layout / size of those classes. * All 100% match except two functions with a pair of registers swapped.
