Well, you got me on this because I'm not an expert on all the file systems
that are used in industry, but this question is a standard OS programming
question that I picked up in Grad School, so I guess the money I spent was
worth it. Without a basic background is OS architecture it would be hard
to explain the problem that doing this presents. Part of this was written
into the last Journal.
