I'm using it and it appears that it's evaluating the Streams when I
call join. I need a lazy flattening of Streams. Is there something
that does this, or should I write my own?

The problem here is that Semigroup is strict in both of its arguments,
so the current implementation of Stream.join is incorrect. It should
really be implemented as an unfold. If you want to tackle it, go ahead
and make a pull request.
