Did they pass review? I have some doubts.
The last time I looked it also broke numactl.

Since they are both performance features their ultimate benefit
is how much faster they make things (and how seldom they make things
slower)
IMHO needs a performance shot-out. Run both on the same 10 workloads
and see who wins. Just a lot of of work. Any volunteers?
For a change like this I think less regression is actually more
important than the highest peak numbers.
