The LimitScanner's use of a sentinel error inside an LMDB transaction aborted the transaction. I instead moved the "limit reached" marker to the cursor returned by Last().

There was a problem hiding this comment.
The new logic looks OK. The PR could have been kept more minimal with just a check for the error and assignment to a bool, but no objections to the explicit return value here, because it does make the code harder to hold wrong.
The extra locking really needs to be removed, however. LGTM if that is fixed.

Changed. Github didn't pick up on that somehow?
