Offers a deterministic one-to-many and many-to-many messaging alternative to DataflowQueue. Internally it wraps a DataflowStream class with a DataflowStreamWriteAdapter and so synchronizes all writes to the underlying stream allowing multiple threads accessing the stream concurrently. On demand through the createReadChannel() method it will return an DataflowReadChannel through which the reader will receive all messages written to the channel since then.
Typical use:
DataflowWriteChannel broadcastStream = new DataflowBroadcast() DataflowReadChannel stream1 = broadcastStream.createReadChannel() DataflowReadChannel stream2 = broadcastStream.createReadChannel() broadcastStream << 'Message' assert stream1.val == stream2.val

Retrieves an implementation of DataflowReadChannel to read all messages submitted to the broadcast chanel. Since multiple parties (threads/tasks/actors/...) may ask for read channels independently, the submitted messages are effectively broadcast to all the subscribers.
