> Use a NIO network lib based on epoll (kqueue under MacOS/FreeBSD) to provide high-concurrency, high-performance network IO

What is "NIO" here? I am familiar with NIO as New Input-Output from Java, which was the extension of the standard library to cover asynchronous I/O. Is the author using "NIO" to mean asynchronous IO? Their use of '"JSP-like" CSP file' elsewhere hints at a Java background.
