The executor keeps a queue of tasks that it should poll. When a task is created, it is polled (1). The task will attempt to make progress until it reaches a point where it would be blocked.

Once a task yields, the executor enqueues the task at the end of the run queue, and proceeds to (3) poll the next task in the queue. IMPORTANT: The executor relies on tasks not blocking indefinitely, as this prevents the executor to regain control and schedule another task.
