> Even after encountering an OP_INVALID, we should check the end of the edit
> log to make sure that it contains no more edits.
> This will catch things like rare race conditions or log corruptions that
> would otherwise remain undetected. They will got from being silent data loss
> scenarios to being cases that we can detect and fix.
> Using recovery mode, we can choose to ignore the end of the log if necessary.
