I worry about hashes because of some previous work I've done and some points made in this article.

HashMemoryBlog

Especially where it says "Perl's hashes are inefficient. You need A LOT of memory if you intend to hash tens of millions of key."

This is a concern for me, because the datasets I'm using are really really gigantic.

And I meant to say, 1,000 elements in each array.
