Re: Paging file

SO, what is the solution to the problem, Leif?

I have begun reading your eBook.  I was particularly interested in how a
program can switch into system state and use fake pointers, and I hear you
talking about the flaw(s) in SLS.

What can IBM do to fix it?  Create a new level of system security?
