OK, in other words, we have to implement this feature as follows:
 (1)Start a sorting thread by SwingUtilities.invokeLater.
 (2)Calling Observer#update to update completion list.

"Whenever possible, you should use invokeLater instead of invokeAndWait."
   http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html#invokeAndWait


The current Completion implementation synchronously(blocking method call) 
updates completion list.

We should have internal logic of asynchronous update of completion list
in case canceling action by hitting Ctrl-G(like emacs minibuffer) or something.

But the external user interface should be synchronous, block user input 
except with canceling action. Later update of completion list may be 
troublesome and embarrassing.
