Detailed Description

A service to deliver a signal to host application.

Typically there'll be just one implementation of this by the main application.

Other parties interested in listening to shutdown may override the default implementation with a broadcast one and have multiple implementations receiving the shutdown signal. Or do message queueing to a set of background threads etc.
