xopen() wants 2 arguments unless you're creating a file, in which case you need 3. Doing varargs for this doesn't really appeal to me (bugs in waiting) so I made an xcreate() that takes 3 args, and had xopen() call it with 0 for the third argument. That way, if we feed O_CREAT to xopen() the permission 000 result should be easy to spot.
