Thanks. That is about what I got so I do seem to understand the
differences right.

For my use case this would then come down to implement solution 3 with
channels instead of my own queues. Well, channels are thread safe queues
just by another name. I think I see now how they make the code simpler
to write.

Channels are a thread-safe communication channel of depth one (i.e. you can only pass one item at a time.) The channel is a primitive that allows reliable synchronized communication between threads. The Reppy book describes in later chapters how to use the channel primitive to build up queues and other, more complicated constructs (like RPCs and multicasting to many processes.)

In fact, you might use the RPC ideas to pass your checksumming requests to worker tasks and receive the results.
