        Nah, I did a test to sustain my affirmation.
        I modified PortLink to show buffer size every time Attach is called. 
Then I added a 33K attachment to AS_WINDOW_HIDE (and read that message 
in ServerWindow of course). Also I put my window to do some 
drawing(window became visible after 2 sec). I forced redraws by moving 
another window above it, or move it outside the screen edge and back.

        The buffer remains at a value above 33K.
