Can I wake a sleeping Mac?

[Victor Eijkhout]

I'm trying to write an alarm clock. So I send a wake message to a 
handler in so many ticks.

Unfortunately my Mac goes to sleep, and the ongoing tick count gets 
delayed until it wakes up. Which is after *I* wake it.

Irony written all over this story, I know.

So, can runrev wake a sleeping computer? I know that it is possible 
in principle, because Apple's software can do it, and I've seen 
RealBasic programs that did it.
