Actually, what's happening here is that the result of invoking new
Service() is being stored with the page instance and used to reset the
service field to its default value at the end of each request.
This isn't quite the same as storing it in the session, as the Service
instance will be carried with the page and used by multiple
*different* clients. In this way, data can bleed from one client to
another.
