You seem extremely knowledgeable about high-performance servers!

Your example is fantastic -- I realize it's written in C, but perhaps you could explain how in the context of a tool like this (current article) might allow it to function as an end-to-end webserver?

What kind of limitations? What are the advantages, security implications? What is it well-suited for?

Really appreciate a reply -- I'm writing a book on architecture design and I'd really love to include some elements from the bleeding-edge of performance -- you clearly know what you're talking about.
