Generally speaking, in lock-free programming, there are two ways in which threads can manipulate shared memory: They can compete with each other for a resource, or they can pass information co-operatively from one thread to another. Acquire and release semantics are crucial for the latter: reliable passing of information between threads. In fact, I would venture to guess that…
