A task can voluntarily suspend itself in the middle of a long-running operation that doesn’t contain any suspension points, to let other tasks run for a while before execution returns to this task.

If this task is the highest-priority task in the system, the executor immediately resumes execution of the same task. As such, this method isn’t necessarily a way to avoid resource starvation.
