I've tried this in lieu of the way I was generating the work units. (def work-units (for [x (range 100)] "88148433eeb5d372c0e352e38ac39aca"))
I know that for is still lazy, so I did this after the binding of work- buckets: (println work-buckets) ; yielded expected result ((88148433eeb5d372c0e352e38ac39aca 88148433eeb5d372c0e352e38ac39aca.... I'm assuming if I can see work-buckets from the print statement that it's fully materialized. This part all happened in less than a second. >From here, all that's left to do is spawn four agents (assigning each a work bucket), send them each a decode function, and the loop over the result set, and I'm seeing the same results as before.
