Shutdown (and Logout) menu items should activate the buzzy cursor (or provide some other visual feedback, perhaps dimming/locking the UI from use). If you trigger these menu items with a number of activities resumed there can be a very long wait before anything visually happens, the user may well start to do other things, or hard power off. With 9 activities open on an XO-1, the time between selecting Shutdown from the central XO home icon and the display visual changing, was between 40sec and 70sec
