It's just really frustrating that they are adding ISA features to make up for the poor security offered by the dominant language. That's not a critique of C either - I understand the history and the fact that it's taken decades to discover the flaws of it and define a better way. I just get frustrated seeing patch after patch after hardware patch to fix a broken design. This one almost seems frivolous given the NX bit, but I'm sure one could craft something to exploit it somehow.
