title: android:orientation="vertical" does not work for TabWidget
body: <p>My app has a tabhost with four tabs, and now I'm trying to make nice layouts for landscape mode. In order to make use of additional horizontal space I want to put TabWidget at the right side of the screen, and of cource all tabs must be one under another (like in a column).
  But when switching to landscape mode all tabs get aligned in a row, it looks quite ugly. How to fix that?</p>
