• Reacting to the completion of an asynchronous operation

Chapter 15 explored the modern concurrency context: that multiple processing resources (CPU cores and the like) are available, and you want your programs to exploit as many of these resources as possible in a high-level manner (rather than litter your programs with ill-structured, unmaintainable operations on threads). We noted that parallel ...
