When designing parallel and concurrent systems, developers invariably face a core architectural dilemma: Multi-Process vs. Multi-Threading. If you learned systems programming in C, you likely remember fork() and join() (or waitpid()) as the default primitives for spawning and managing execution units. In the early days of Linux, POSIX thread implementations were notoriously fragile, making process cloning the de facto standard for parallelism. However, as operating systems matured and prod...
