pickle_atomic: use atomictempfile to avoid duplicating hg functionality atomictempfile takes care of a whole bunch of things we need, including atomic renaming, putting the tempfile in a reasonable location (with a reasonable name), and file mode copying. Thanks to mg for pointing out that we could use this instead of rolling our own file mode handling.
