-// Atomic operations are performed in a single step by the CPU. It is
-// impossible for other threads to see the operation "half-done."
-//
-// Some atomic operations can be combined with different types of memory
-// barriers called "Acquire semantics" and "Release semantics", defined below.
-//
-// Acquire semantics: Future memory accesses cannot be relocated to before the
-//                    operation.
-//
-// Release semantics: Past memory accesses cannot be relocated to after the
-//                    operation.
-//
-// These barriers affect not only the compiler, but also the CPU.
