I suspect that is going down a wrong path.

We use the sequence:

	fd = creat("temporary location");
        write(fd, ...);
        close(fd);
        rename("temporary location", "final location");

in quite a lot of codepaths.  I think they can be factored out,
to take the "final location" (and perhaps a suggested temporary
directory) as an parameter, and that code can check that "final
location" is a symlink to somewhere else and create the
temporary next to the target file.
