interesting - I didn't even realize this was for use in a battery powered device. I guess there are a billion things it could be used for, and there are probably billion different ways to do it.

So, what is really the best (hopefully somewhat platform independent) way to accomplish this? Is there one? A project that I worked on a few years ago would have been best done if I had known how to really take advantage of a Sun kernel, but I didn't, and neither did anyone else at the shop, so we just used the clock. It held up well enough, but, we did consider exploring options using traps and signals.
