    The preview copy of the O'reilly book on git had some great diagrams as well of how the object model works and the DAG.

    What I finally grokked is that the stash is just the NEXT NODE in the DAG before it's been hooked onto the end. All a commit does is set the stash's parent pointer equal to the current branch pointer and set the current branch pointer equal to the stash.

    It's not really an "extra layer" -- it's just the next node under construction.
