Here I will provide some context on how the concept of multiplexing (or joining) channels got into my life, how it changed how I design concurrent algorithms and present an implementation of that idea comparing with a more common alternative. I have a feeling that this may be something well known by people who have experience with concurrent algorithms, but since there is a chance that I’m not the only person oblivious to this idea I’m going to try and explain how I discovered it and then had some fun with it and how I think it now helps me, in some cases (it is not a silver bullet), to write simpler concurrent code.
