Natively supporting this mode of operation is not a bad idea in its own 
right. This is sometimes preferable to the interruption approach because it 
guarantees that the consumers will drain the queue before shutting down (and 
that guarantee comes for free, no effort is required on part of the user, as 
long as the producers are shut down beforehand.)

You will also need tests.
