If you get a chance, also considering adding a luvit version. It's very node-like, but with the fast luajit VM. In my tests it's about 4x faster than nodejs 0.4.x on 64 bit machines. https://github.com/creationix/luvit

I haven't implemented fd passing yet so it will be stuck on a single core, but that will change soon. Also lua makes it possible to add real threads to the system if desired.
