Description:
IteratorImpl currently created a new Object[] for each row returned from  a query. For single column queries the iterator then just pulls the single value out of the array before returning it. This patch removes the array creation for single column queries.

BTW, why was the decision made to use a new array for each row? Even in the case of multiple value queries, it would be much more efficient to reuse the same array. The user could copy the values into a new array if so desired. It's probably too late to change this, unfortunately...
