> If the first 4 bytes of the checkpoint are overwritten, then the current
> sanity check will miss it because we read the first long and then cast it to
> an int, missing the first 4 bytes when we check the version. First 4 bytes
> being corrupt could indicate further corruption in the checkpoint which
> cannot be verified because the remaining data consists mostly of pointers to
> files, which if not used are simply ignored by the replay mechanism
