That is one of the advantages, yes. As far as I can see though,
there isn't like *huge* amounts of things you can simplify. And
if it is just a matter of removing a few branches from a few
cold paths, then it isn't necessarily a good reason to push
branches into the slab and page allocators.
I'm not saying we definitely should go one way or the other, I
would just like to wait and see.
