// things generally work fine here -- the UI thread is done by the time the test is done.
// In landscape mode, though, since the launcher is in portrait mode, there is a lot of
// extra work that happens in our UI when the app launches into landscape mode, and the
// UI is often not done by the time the test finishes running. So then our teardown
// nulls out the Factory, and then the UI keeps running and derefs the null factory,
// and things blow up.
// So ... as a cheap hack, sleep for one second before finishing the teardown of UI
// tests, but only do it in landscape mode (so that developers running it in portrait
// mode can still run the tests faster).
