I don't think we have increased the default stack size in decades,
it's still 8KB on almost all 32-bit architectures (sh, hexagon and m68k
still allow 4KB stacks, but that's probably broken). I would actually
like to (optionally) reduce the stack size for 64-bit machines
from 16KB to 12KB now that it's always vmapped.
