After some thought, I think I've come up with a good enough way to
preserve this functionality, without having to fork another process just
to do the test.
Because the test is NOT being used by a root process as a prelude to
actually doing something with the file - it's merely trying to find
information about the file - I think we can get away with a little bit
of code that stat()'s its way through the enclosing directories to the
file itself, checking that the given user has read access.
