Found the synchronization problem in the affine thread pool - the auto reset event was being set twice before even a single thread pool thread made it through the WaitOne() - fixed by using a semaphore; implemented a semaphore that should work in the XBox 360; wrote unit tests for said semaphore; added messages to the affine thread pool's unit tests to make debugging easier
