Had been using this quite some time ago, it is sad that it has only 1-CPU support, preventing some SMP bugs from emerging.

Wonder if it's hard to make it SMP, if too many places use something like #ifdef CONFIG_ARCH_IS_UM to tell whether it is single CPU, it might be hard.

SMP has been implemented recently and is queued for the next release.
