Careful here too.  Store the pointers as offsetts from the address where
teh segment is attached.  This will allow a different process who has not
attached the segment at the same address (by choice, or just can't do it) to
still use the data.  You will experience a slight performance hit, but a slow
working program is better than a fast one that does not work.
