And to further note - these benchmark measure, in effect, purely swap
overhead. In a production environment with a lot of non-swap work, as
long as the gap is close enough I think we would be fine, even for a
hostile case like a fast swapfile-backend (I assume SSD swap's
bottleneck will be the IO mostly).

I will stare at your responses to see if there is other benchmark I
can play with, but it would be very helpful if you can share your full
suite :)
