The below patch implments in-kernel preemption for the i386 port.
Is in-kernel preemption really worthwhile on multiprocessor
Yes, I think so. There are long/slow code paths within the kernel.
Right, but is it better to handle these by preemption or by setting up

I think it's better for the scheduler to handle this for us, rather
than having to identify each of those and figure out where the right
places to yield are.
