I will be running this only as often as practical. Meaning if it takes 2 weeks to produce the data I need, then it would be run every 2 months or longer. If it could produce it in, say, just a few days, then I would re-run it with updated data at least every month. The data set that this program chews on grows every month, and I foresee this program to be used for years to come.

I work with x86_64 machines (linux) and it'll be about a week before I can get the program completely re-tooled to use Bit::Vector. I shall email you!
