Do we know anything more useful about this?

Since Perl uses linked lists when collisions occur, most (all?) of this new work seems irrelevant?

What are the methods used in other langauges / implementations?

In my brief research, it seems the only marginally questionable thing that Perl does is not resize based on collisions. It seems, in the worst case, all entries go in the same bucket, but a resize isn't triggered until 75% loading factor is reached?
