> Every time a NIO thread wakes up on selected keys, a new iterator is created since selector
returns a Set.
> There is a technique that makes it possible to avoid new iterator creation, that is implemented
in Netty.
> For details, see io.netty.channel.nio.NioEventLoop and processSelectedKeysOptimized method.
