Document why we notify all streams when sending a single message #57

It's unclear to me why all streams are woken up instead of a single one when sending a message. (That is, why don't streams and recv behave in the same way, when the stream is typically essentially "polling recv forever").

Would it be possible to document that further?

Thanks,
