This would make free space reuse a lot cleaner. The idea is:

  • Leave nodes in-memory, but make them shareable still by future proposals
  • Expire the oldest revision BEFORE allocating space for the committing revision, avoiding all freelist updates

This design change also sets us up for not persisting some of the revisions, similar to what geth does.
