while i dont want to jump to conclusions without looking at some
profiles, i think the SLUB performance regression is indicative of the
following fallacy: "SLAB can be done significantly simpler while keeping
the same performance".
I couldnt point to any particular aspect of SLAB that i could
characterise as "needless bloat".

I suppose if the NSA had 20,000 2Ghz processors in the basement
cranking for 10 years, then 50% of the time *after* they did a black
bag job to crack the random pool state, they could get the last 80
bits generated from /dev/random, but it just seems that if you are
assuming the power to grab the pool plus add_ptr, there would be much
more useful things you could --- like for example having the black bag
job trojaning the software to grab the private key directly.
