Message:

Modified Scoped Singleton concept: Derive from Singleton normally, but place an important pre-main() instruction in the source file: ManageScopedSingleton(className, scope) (it's a macro).
This causes the Singleton to be created and destroyed with the Scope. Thus if a Singleton c'tor throws, it is much easier to react accordingly.
