I think that highlights one of the issues with Linux being essentially just another clone of Unix, and thus being constrained by its limitations - both technically and in mindset of its developers. Whereas NT was a fresh new design, by seasoned operating systems designers and implementers, who had seen the shortcomings of the Unix model (and others) and not only knew what to do differently to improve on these, but actually wanted to and were permitted to as well.
