There could a problem with that... Is it possible for there to be a race? I have to call the function twice per cache op: once to set the file creation security ID and once to restore it back to what it was.
However, what happens if I can't restore the original security ID (perhaps the rules changed between the two invocations)? I can't let the task continue as it's now running with the wrong security...
