> IMO the difference between threads and processes is somewhat academic. Shared memory vs. isolated memory is a huge difference. You use completely different sync/protection/IPC approaches with each, so programs look very different. And the copy-on-write optimization of logically isolated memory doesn't effect that. The beauty of it is that it speeds up forking and saves memory without changing your IPC-based programming model.
