This is something I noticed with Go. Channels are great and all and occupy a decent chunk of the tutorials and whatnot, but they see to be rarely used apart from a fairly cumbersome way of handling timeouts and cancellation. It seems if you stick concurrency in your libraries you end up in knots, and its left up to the code that uses the libraries to wire up all the synchronous & blocking bits.
