// Provides the interface between one or more Suppliers and the
// Event Server ACE_Stream.
//
// = DESCRIPTION
// When used on the "reader" side of a Stream, this Router Task
// simply forwards all messages up the stream. When used on the
// "writer" side, this Router Task queues up outgoing messages
// to suppliers and sends them in a separate thread. The reason
// for this is that it's really an "error" for a
// <Supplier_Router> to send messages to Suppliers, so we don't
// expect this to happen very much. when it does we use a
// separate thread to avoid taxing the main thread.
