NAK, this file is incorrect.  As noted in a previous email, the revoke block
should itself be revoked (and the replay restarted) if we encounter corrupt
blocks.

Silly /me didn't consider that revoke records aren't intended to unilaterally
kill journal blocks; they only make sense if there's a subsequent transaction
also writing the block.
