- * A semaphore is a locking primitive that protects resources. It is created
- * with an initial number of resources (which may be 0), and offers two
- * primitives to acquire and release resources. The acquire() method tries to
- * acquire a number of resources, and blocks if not enough resources are
- * available until they get released. The release() method releases a number of
- * resources, waking up any consumer blocked on an acquire() call.
