- Just a thought, but maybe the application shouldn't be updating the

- "works well" is somewhat subjective, but just as a point of reference,
- I've seen preemptive multitasking systems "work well" in a visually
- interactive environment.

- Some companies are shipping true SMP machines. SMP usually refers to
- an architecture where N processors have equal access to memory and
- IO devices. This is in contrast to other MP architectures such as
- master-slave.
