I am getting a paranoid thought: shouldn't that segment be defined restricted 
with the RSTD option? Defining large EW/EN segments basically gives out the 
authorization to enlarge a users Vsize without requiring directory 
authorization. With only below-the-bar segments that capability was limited, 
but with above-the-bar segments this can add up. I can envision a system being 
brought into great trouble by linking and filling all unrestricted EW segments. 
The current default is rather Windowish allowing all to anyone and is half a 
security hole. Maybe above-the-bar EW/EN segments should default (require?) to 
restricted. You listening, Endicott?
