For Python 2 it's not possible because Python's internal file API uses
fopen(3). fopen(3) has a limited set of flags and exclusive create isn't
one of them. You'd have to rewrite larger parts of the API.
Python 3's io library is build around file descriptors returned from
open(2). It shouldn't be hard to write a 'c' flag for io.
