seems to me... channels are for language-handled concurrency which is able to then, transparently, be parallel, readers are a single threaded thing that mimics concurrency, they do it explicitly.
so you need to 'drive' the readers by calling them all in a loop, handling any none zero length, the channels can be 'selected' because the language handles calling the right piece of code as other, possible threaded code, drops something on a channels.
