// Base class for Factories that take an opaque pointer and return some service
// on a one-to-one mapping. Each concrete factory that derives from this class
// *must* be a Singleton (only unit tests don't do that).
//
// We do this because services depend on each other and we need to control
// shutdown/destruction order. In each derived classes' constructors, the
// implementors must explicitly state which services are depended on.
