I have worked in JAVA, PHP, Net, and they all handle non-blocking. Java specifically (for example), doesn't handle non-blocking IO but it has a very efficient client-server request model and we can use that. If your argument is that once the request/thread is created we then need to wait, sure we do - but that doesn't really hinders me from anything.
Just to be clear, are you suggesting that non-blocking approach if JS and being able to use call backs allows node.js to be more scaleable?
