An example when `Task.Yield()` is useful

channels.cs

var ch = Channel.CreateUnbounded<int>();

var producer = Task.Run(() =>
{
	for (int i = 0; i < 500_000; i++)
		ch.Writer.WriteAsync(i);

	ch.Writer.Complete();
});

Task.WaitAll(
	Read(1),
	Read(2),
	Read(3),
	producer);

async Task Read(int id)
{
	var dc = new DumpContainer().Dump(id.ToString());

	await Task.Yield(); // to prevent blocking when the producer has already written elements
	
	await foreach (var x in ch.Reader.ReadAllAsync())
		dc.Content = x;
}
