The technique advocated by Theodore Ts'o (save to temporary then rename) discards metadata. What would be useful is a simple, generic way in Python to copy all the appropriate metadata (ownership, ACLs, ...) to another file so the temporary-and-rename technique could be used.
On Windows, there is a hack in the file system that tries to track the use of temporary-and-rename and reapply ACLs and on OS X there is a function FSPathReplaceObject but I don't know how to do this correctly on Linux.
