Sorter can have runaway memory consumption as it never frees local allocations made in comparator_.Less(). In addition, it doesn't check for errors generated during expression evaluation so it may keep sorting even after failures have occurred. This change fixes the problem by freeing local allocations for every n invocations of comparator_.Less() where n is the row batch size specified in the query options. Various error checks are also added to return early if any error is encountered.
