I think we're talking about two separate issues.

One is how to safely create a file (without race condition) so that we
really create _that_ file and not another one via a new symlink. The answer
is O_EXCL.

The other issue is how to create the file with the right permissions so that
we don't leak information. I guess I proposed a cleaner solution for this
than the current one.

I can't see any correlation between these two issues.
