Ah yes, I remember reading about this automatic flushing thing. I don't know how the caches actually work on most of our PPC's, but the fact is, we don't have aliasing issues, so I can safely ignore it for a bit longer :-) There are some aliasing issues with the instruction cache specifically on some 4xx models but that's irrelevant to this discussion (and I think we handle them elsewhere anyway).
