 // This class provides the following functionality:
 // Given a top-level window handle, it enumerates all descendant windows
 // of that window and, on finding a window that belongs to a different
 // thread from that of the top-level window, it tests to see if that window
 // is responding to messages. It does this test by first calling the
 // IsHungAppWindow API and, additionally (since the IsHungAppWindow API
 // does not deal correctly with suspended threads), send a dummy message
 // (WM_NULL) to the window and verifies that the call does not timeout.
