I'm not interested in anything more complex for my experiments - at
least not right now. I kind of expect blocking NIO sockets to be
comparable with blocking java sockets and apr sockets for normal  I/O
- maybe 1.4 has some problems, but probably 1.5 or 1.6 will improve

I could try reading the http request in non-blocking mode - but what's
the point when the servlet will spend most of the time in service and
writing to a blocking stream ? It's more interesting how to do some of
the service() with a non-blocking socket, for files and few other
