I asked about this a while back.  My conclusion was that "end" is 
definitely exclusive, and while "avail_end" is actually implemented as 
inclusive everything calls it with end == avail_end, so they wouldn't 
notice even if avail_end were ignored entirely.  Changing it so that 
avail_end is treated as exclusive would probably be a good idea.
