BTW, can we get rid of this concept at all? As far as I understand this 
situation exists only because of cached write that causes progress bars 
and other visual indications to end before the actual process ends. I 
believe that switching off write cache for removable drives will greatly 
reduce chances for the user to mess things up by unplugging a drive. Or 
am I wrong?
