I opened http://crosbug.com/2264 to track this.

Can we just wait for cryptohome to be mounted or is WM starting asynchronous? 
This seemed adequate when I ran into this on a slower HDD device:

+            time.sleep(20)
+
+        # TODO: Set these in a single, standard place for all tests.

Perhaps autox.AutoX() can do it, and take params for these values.  The ones
used here could be the default?  We can store them in chromeos_constants.

+        os.environ['DISPLAY'] = ':0'
+        os.environ['XAUTHORITY'] = '/home/chronos/.Xauthority'
+        self.autox = autox.AutoX()
+
+        # Create a window and check that we switch to it.
+        win = self.autox.create_and_map_window(
+            width=200, height=200, title='test')
+        info = self.autox.get_window_info(win.id)
+        self.__check_active_window(win.id, info)
+
+        # Create a second window.
+        win2 = self.autox.create_and_map_window(
+            width=200, height=200, title='test 2')
+        info2 = self.autox.get_window_info(win2.id)
+        self.__check_active_window(win2.id, info2)
+
+        # Cycle backwards to the first window.
+        self.autox.send_hotkey('Alt-Shift-Tab')
+        self.__check_active_window(win.id, info)
+
+        # Cycle forwards to the second window.
+        self.autox.send_hotkey('Alt-Tab')
+        self.__check_active_window(win2.id, info2)
+
+        # Now destroy the second window and check that the WM goes back
+        # to the first window.
+        win2.destroy()
+        self.__check_active_window(win.id, info)
