Pipeline handler ordering and other questions

Specifically, about this: What if there will never be more data available from the network? Will there be a timeout at some point, or will there be an error or any such thing? How do we handle the case in which there is no more data following to decode?

When we receive EOF we'll call decodeLast. This allows you to produce any final values that you may require, or to throw an error if the data is invalid. There's a default implementation of this in terms of decode, which is why you may not have noticed this method yet.
