(from easy to more complicated):
- Disable direct reclaim with 4K stacks - Do direct reclaim only on separate stacks - Add interrupt stacks to any 8K stack architectures. - Get rid of 4K stacks completely - Think about any other stackings that could give large scale recursion and find ways to run them on separate stacks too. - Long term: maybe we need 16K stacks at some point, depending on how good the VM gets. Alternative would be to stop making Linux more complicated, but that's unlikely to happen.
