Any x86-32 path unsafe with 4K stacks is almost certainly unsafe with 8K
stacks because the 8K stacks do not have seperate IRQ stack paths, so you
have the same space but split. It might be less predictable on 8K stacks
but it isn't absent.
Understood, but isn't that an argument pro interrupt stacks, rather
than one against 8k? wli has a patch to break out the interrupt stack
feature from the 4k/8k choice.
