Hey, both of you are right, but for different parts of the 
equation.  Data can be accessed in any memory page regardless of 
the memory pool it is in.  Program specific logic and buffers 
cannot be accessed across memory pool boundaries, IIRC.  

IE, if I've got 2 memory pools for my interactive work and user z 
loads up pgma in pool 1 and then user y loads up pgma in pool 2, 
there will be two copies of pgma in memory.  If user z reads 
record 12345 and then user y also reads 12345, user y will read 
from memory and not perform another fetch from disk.
