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.
