I guess that a simple way to cut the discussion short would be to have a first implementation, and run some benchmarks to measure the benefits. I can certainly see the benefit of cacheline-aligned data structures in multithreaded code (to avoid false sharing/cacheline bouncing): I'm really curious to see how much this would benefit in a single-threaded workload.
