yes? and how many compilers do you know that would be even remotely able
to optimize such cases? i'd be too interested in knowing how they do it.
honestly, i think trying to apply NUMA as an example here is a dead end.
using complex structures transparently might be used on segmented
architectures where offset calculations with segments are impossible
(e.g., i286 (16 bit) protected mode). i don't think this applies to any
architecture [prospectively] supported by kde.

Hi! I'm a .signature virus! Copy me into your ~/.signature, please!
Chaos, panic, and disorder - my work here is done.
