      Description

      Saved caches are not covered by a checksum. We should at least emit a checksum. My suggestion is a large checksum of the whole file (convenient offline validation), and then smaller per record checksums after each record is written (possibly a subset of the incrementally maintained larger checksum).

      I wouldn't go for anything fancy to try to recover from corruption since it is just a saved cache. If corruption is detected while reading I would just have it bail out. I would rather have less code to review and test in this instance.
