Also... what are you doing it for? There are a number of legitimate<br>
uses, but it's also a common race condition -- just because something<br>
is readable at the moment you checked doesn't mean that it'll still be<br>
readable when you try to read it. So if you really depend on it being<br>
correct, then you'll have to just try to do the operation and check<br>
failure then.<br>
