> When a read needs to do more than one retry (due to short reads), the
> originalCount is not preserved by the retry leading to returning more than
> the requested number of columns.
> Moreover, when a retried read checks whether more retry is needed, it doesn't
> compare the number of live column retrieved against the original number of
> columns requested by the user, but against the number of columns requested
> during the retry, making it much more likely to actually do one more retry.
> This catch by the two tests 'short_read_test' and 'short_read_reversed_test'
> at https://github.com/riptano/cassandra-dtest/blob/master/consistency_test.py
> that are failing intermittently.
