Btw, Faulting is one of the things I hate in OR Frameworks.

I was told on Cocoa list, that its true that if table T5 has million
records, then system prepare million small RAM objects for future faulting.

IMO this is huge overhead.
IMO this is limited way by hardware.

So is this true that all million objects are prepared?
