foo = tempfile.NamedTemporaryFile(delete=False)

I don't know if that is useful in this case.  I guess there's still a
race, in that if Norton AV decides to walk that directory and examine
that file, you've been gotcha'd.  On the other hand, you can assume
that no user in their right mind will be sitting there clicking like
mad on a Word file dialog trying to open the file, so Maritza's
assumptions are much more likely to hold true.
