> IndexerMapReduce has the option to skip DB_NOTMODIFIED but legacy code also skips FETCH_NOTMODIFIED and the latter is not optional. We can keep the check but that should also include FETCH_NOTMODIFIED. Relying on FETCH_NOTMODIFIED isn't very useful anyway because since 1.5 orso we can safely rely on DB_NOTMODIFIED as it is properly set in the CrawlDBReducer.
