Re:Not an important question really. (Score 1)

Well, I think it's important to remember that while OS X draws a lot from NeXTStep, it is by no means limited by it. There are massive amounts of BSD thrown in there and the kernel itself is Mach, so... while your concern does have validity, at the same time I would tend to think that given so much time, the open sourcing of Darwin and the combination of tech from BSD and Mach should have eliminated such a significant problem. Besides that, Apple is gambling heavily on this OS, so problems like this should/would have been at the top of the priority list.
