I've compiled it and had a brief look at this. I have got only this to say, it is a very important evolutionary step in server-side coding and coding in general. Really impressed! Though I have one more question, how do you handle concurrency? I mean, mutex, locks, etc. Don't get me wrong, I'm not being picky, just wondering what could be the best solution for this.

Edit: Or Events in EventEmitter are being executed one at a time, so there is no need for locks?
