Well that's what I meant by adding an optional argument to Eject(). It's easier 
to implement than a new method, though the latter seems cleaner semantically: 
closing tray is almost opposite to ejecting. Using the analogy, 'gnome-mount -u' 
equals 'gnome-umount', but we still chose to have separate methods for mount and 
unmount.
