I tried this earlier on when it became apparent the project would be sucking up great quantities of memory - with very little success. In fact, I think it changed the memory usage by less than a few hundred kilobytes...
This was some time ago, the data set has changed greatly. Perhaps I should try this again and would benefit more from it with a more diverse data set.

I don't even begin to understand that second paragraph. It amazes me how much I can do in perl, and how remarkably little I truly understand about the workings of it all. How embaressing.

My thanks,
JP
