+** Purpose:
+**
+** Test to ensure proper operation of the GetCurrentThread()
+** API. The test launches a thread in suspended mode, and sets
+** its priority to a non-default value using the handle returned
+** by CreateThread(). The new thread calls GetCurrentThred() to
+** retrieve a handle to itself, and calls GetThreadPriority()
+** to verify that its priority matches what it was set to on
+** the main execution thread.
