If an object doesn't exist in the cache it meas that either it was not yet
loaded at all,  or it was loaded but it's now mark as "invalidated" (for
example the transaction in which it was loaded fresh has terminated).

So I'm note sure what you mean in you question, but I don't think anything
more that could be cached (in terms of key->object values).
