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...
