We'll see. I suspect that all large-memory users have long since upgraded to x86-64 (rule of thumb: if you are upgrading kernels today, you probably upgraded hardware ten years ago), and that this may be a non-issue today. But only time will tell. I certainly prefer "keep it simple" over theoretical concerns. It's why I prefer that unconditional stack limit too - we may have to make it conditional on suid'ness or something like the ELF PT_GNU_STACK setting, but before over-designing things, let's see if anybody even cares.
