I thought about it when I did that and rejected the idea,
but maybe it's because I was benching the deinterlacers differently and
needed to link with the core for other purposes.
And so I couldn't have another implementation of vlc_CPU, as there were
already 2 with a weak attribute on one of them, IIRC.
(that was many months ago now, the reflections behind those patches aren't
so fresh in my mind anymore)

That's not the case anymore, and I don't think I need the core for anything
else here anymore anyway, since I changed the way to bench that,
so it could be fine now, I need to actually look into it again.

You should think about doing some meditation dude.
It's not normal the get "really pissed", as you say, over such things.
