-// A stream<> is the producer side.  It may call produce() as long
-// as the returned from the previous invocation is ready.
-// To signify no more data is available, call close().
-//
-// A subscription<> is the consumer side.  It is created by a call
-// to stream::listen().  Calling subscription::start(),
-// which registers the data processing callback, starts processing
-// events.  It may register for end-of-stream notifications by
-// return the when_done() future, which also delivers error
-// events (as exceptions).
-//
-// The consumer can pause generation of new data by returning
-// positive integer; when it becomes ready, the producer
-// will resume processing.
