very small test

When an app that is sleeping in WaitMessage receives a non-queued message, it
should be awaken first. Then wine should wait it to reenter before dispatching
the non-queued message (wait until the app calls GetMessage or PeekMessage?).

For a broader discussion see "Does wine send window messages without waiting
apps to reenter userdll?" thread in the mailing list. Attaching a test that
shows the incorrect behavior.
