> There is a reason that multicore cpus do not look like networked machines. They don't? In practice cache coherency is a correctness mechanism; actually using shared memory concurrently R/W is problematic, performance wise. That's how we get scatter/gather-style systems, specifically to avoid concurrent R/W.
