CoreAnimation is part of the story, multithreaded rendering is another. On OS X, each view (or, at least, most views) have a CA layer attached and so can independently render into that layer. A renderer thread can composite the result. Views marked as not supporting threaded drawing are all rendered in the same thread (typically because they interact with controllers that are not thread-safe), but this isn't necessarily the same thread as the thread that composites all of the results together. We can't do that with the current drawing model in GNUstep, because every view renders directly into the target window.
