I am a little confused here.  When you talk about I0MMU addresses, are 
you talking about memory addresses or disk addresses?  ISTM that 
protecting memory of lower privileged programs is useless if a higher 
privileged program can force a page out to disk, then can read the data 
from the disk drive itself.  Of course, the same is true for data 
written to disk by a lesser privileged program.  If the higher 
privileged program can read the file, then it can compromise security.
