Not the place to argue about it here, but I'd rather continue fixing the kernel latency problems if any (we did fix a lot recently) that just preempting when in kernel space. Also, that force all of the SMP stuffs on UP kernels, thus slightly increasing overall kernel overhead on non-SMP setups. Ben.
