11.2 Synchronization

Racket’s synchronization toolbox spans three layers:

synchronizable events — a general framework for synchronization;
channels — a primitive that can be used, in principle, to build most other kinds of synchronizable events (except the ones that compose events); and
semaphores — a simple and especially cheap primitive for synchronization.
