It turns out my main problem was in fact a dumb coding error I had in a function wrapping the http-kit send! function, so that I wasn't actually sending anything to the socket under certain circumstances - apart from that the code was seemingly sound.
I appreciate the replies, however. Aleph looks cool - will need to check that out.
