Please don't, the executive handle table structures are public and 
shouldn't be changed. Plus, the fifo list is index based, which means 
there don't have to be special operations when duplicating/inheriting a 
handle table, they can be copied without recalculation or anything. I'm 
going to mark CIDs as invalid for a certain time instead of deletion, 
which should fix the issues.
