-------------------------------------------------------------
I confirm that with Postgres, the updateCount returned in the
BatchUpdateException can be positive, although the rows are not inserted.
It also seems that the proposed patch makes {{concurrentBatchUpdate()}} perform
better, but I still see occasional failures.
EDIT: these failures appear to be causes by CHUNKSIZE being < 100 (the number
of documents being inserted by the test). Using CHUNKSIZE == 128 makes the test
pass, making it == 10 makes it fail more often.
