Node.js looks interesting, BUT I must miss something - isn't Node.js tuned only to run on a single process and thread?

Then how does it scale for multi-core CPUs and multi-CPU servers? After all, it is all great to make fast as possible single-thread server, but for high loads I would want to use several CPUs. And the same goes for making applications faster - seems today the way is use multiple CPUs and parallelize the tasks.

How does Node.js fit into this picture? Is its idea to somehow distribute multiple instances or what?
