+/**
+An generic active object that can be used to wait for an iStatus to be signalled.
+This has a similar effect to User::WaitForRequest(), but works without
+blocking the thread (which allows other active objects within the thread
+to continue).  Instead, a nested active scheduler loop is used.
+
+To use a CActiveWaiter, pass its iStatus to an asynchronous method, as usual.
+Then call WaitActive() instead of SetActive().
+
+The call will block until the asynchronous completes.
+
+E.g.
+
+void CMyClass::Foo()
+{
+	CActiveWaiter* waiter = new(ELeave)CActiveWaiter;
+
+	iAsyncObj->Bar(waiter->iStatus);
+	waiter->WaitActive();
+	
+	delete waiter;
+}
