Hey, "sigh" right back at you, Alexey!

I am not saying I want to skip "compile testing", I'm just stating the
obvious fact: for a header such as slab.h that's implicitly needed in
pretty much everywhere, it's very difficult to find all the relevant
broken configurations. I don't see the benefit of breaking the world
for this cleanup as Ingo's suggestion will eventually get us to the
exact same situation _without_ causing tree-wide breakage.
