Where the artifacts show up is where surfaces are lit mostly or entirely by bounced light. In any case where you have shadows turned off for any light, or lit directly by a fill light, the artifacts may be harder to notice or not there. This means when you have an IBL light in your image, and it has shadows turned off (which is typical, as far as I'm aware) then it may obscure or prevent this particular render artifact I've been complaining about. This doesn't mean it's a fix all technique though.

f.ex
If I remember correctly, Stefan Werner (stewer) was explaining that the renderer automatically disables AO on lights, when indirect lighting is enabled.
