> The ds spec (in 4.3 compendium, 112.2.2) says we should first register the service for an immediate component, then create the implementation object.  currently we do the reverse.  Following the spec means we have to use a ServiceFactory even for immediate components but it makes the delayed and immediate code much more similar.  There is one behavior change for circular references, see CircularReferenceTest.test_A11_B0n_immediate_A_first  where B gets an A reference currently and doesn't when we follow the spec.
