I haven't looked into the talk, but I can say this: D offers atomic operations like loads, stores, fences and CAS. They are the lowest level you can go and the responsibility to be informed about the caveats lies with you as the programmer. I recently wrote a mostly lock free circular buffer and on the D IRC channel there were a few helpful people who made me aware of how multi-core CPUs and caches work. Fortunately on x86 architectures at least, atomic operations are pretty sane and fast. Other threading options in D are classical mutexes and conditions or thread communication through message passing, which is at the highest level and really hard to mess up. :) -- Marco
