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.
