11 Concurrency and Parallelism

Racket supports multiple threads of control within a program, thread-local storage, some primitive synchronization mechanisms, and a framework for composing synchronization abstractions. In addition, the racket/future and racket/place libraries provide support for parallelism to improve performance.
