public Task Delay(TimeSpan timeSpan, CancellationToken cancellationToken)
Returns a task which will complete after the given delay. Whether the returned
awaitable is configured to capture the current context or not is implementation-specific.
(A test implementation may capture the current context to enable reliable testing.)
