    Description

      I don't have a test case yet, but I noticed in a SelectQuery with implicit DISTINCT (due to a qualifier on to-many), if the root entity has columns that force Cayenne into outside-of-db distinct check (e.g. CLOB columns), I am getting fewer results than the fetch limit. This is due to fetch limit being applied inside the inner result iterator (JDBCResultIterator) not the outer filtering iterator (DistinctResultIterator)
