Begin to "leak" the changes to the registry and supporting subsystems to resolve the flood situation and support abnormal terminations. These changes just define a new message structure for returning all startup/shutdown information in a single broadcast-like transmission. Shouldn't have any impact on existing code as the message object isn't used yet.
