Here are a couple of diagrams to show how Checkpointing v1 behaves so far.
1. Shelve, Unshelve
Shows a difference between how Shelving-v1 worked and how it works in
the new sheving-and-checkpointing design. Note that Unshelve no longer
deletes the shelf. Shelving again would create a second version "foo 2".
2. Checkpoint, Revert, Restore
Shows how checkpointing and restoring works. Note that a 'revert' is
needed before restoring.
