>
> A checksum allows us to validate and ignore missing/corrupt journal files
> (both of which are optional). It is too late to enable checksumJournalFiles
> after the fact of corruption. Best to have it on by default and take the
> small performance penalty so that in the rare event of corruption we have
> some options. Folks who don't care about the integrity of the journal can
> disable it.
