So you want a DequeueEverythingButWaitIfThereIsNothingThere() ?

That should be straightforward to implement as a helper function. We 
could add it to the library, but I am curious about the use case here - 
I would have thought that most apps process messages individual rather 
than in blocks.

Btw, you do realise that the Dequeue() operation is client-side only, 
right? i.e. it is simply manipulating a client side buffer which is 
filled as and when the client receives a message from the server.
