not an algorithmic improvement. It does the same basic algorithm of test until it can insert the data, but instead of only tracking the first free entry (and recomputing it each pass). It tracks all free entries reducing the number of comparisons done and the table grows in size. This may actually result in a small loss on small tables, but is a win for larger tables.
