What is the "necessary" alignment can change with every new CPU, so can
you tell which alignment it is exactly that it provides (I also find
that formulation of "malloc provides needed alignment" quite stupid,
since AFAIK with Intel CPUs you could upload microcode that needs 1GB
aligned memory - sure, probably noone wants that, but malloc sure won't
provide suitable alignment for that!)
