ProcessorSelector, which doesn't add any Processor to process occurred IOEvent. Connection I/O events should be processed explicitly by calling read/write/accept/connect methods. Setting StandaloneProcessorSelector has the same effect as setting StandaloneProcessor, though if StandaloneProcessorSelector is set - there is still possibility to overwrite processing logic by providing custom Processor.
