Well now that I committed myself , I have question for you Alan,,
because I know you know the real answer.


Normally, when we talk about VM OSs we discuss a memory space and an
address space. VM is supposed to be mapping pages or segments from the
address space to the memory space and reverse. I was surprised at your
saying that segmentation is not being used in Linux. If it is paging
that is being used where is the address space that the pages reside in.
