 PV> I have three questions

A very simple method (in my eyes) would be to "open" the files in
a "deny-all" 
mode and keep them open. Now of course this assumes the task "opening" the 
files can't be closed.
    And of course, I'm just looking for a quick and dirty way. But it would be 
easy enough to code a program which opens files and keeps them open and 
perhaps a selective way (semaphores?) to close certain files for access by a 
specific task.
    Just a shot in the dark, so if you shoot back warn me to duck ..

Dave...
