Lennox and vs D File Systems - Off Line Up Dates?

Some modern lenox systems actually do this now, off line up dates. It is increasingly more common in the lennox world, and i don't like it. If you've got a file open and you deleat that file while it's open as roote, you are absolutely allowed to do that. Now what happens is all the processes that have that file open that you remove, they still have access to that file exactly as it was on disk for as long as they're running.
