Comment 14 for bug 1381713

One thing that comes to mind is that any check that doesn't actually carry out the intended action (such as opening a file) is subject to race conditions. Ideallly, what I would like to say is "open this file for me as if I had the following privileges". As is, I think all I can say is "would I be allowed to open this file with the following privileges?" If the answer is "yes", by the time I actually go an open the file, it may not be the same file anymore. This seems exactly analogous to access(2).
