Questions About Scheduler Library....

I've looked at the Scheduler library, and it looks very interesting, but I'm curious about some of the finer details of how it actually works. Does anyone here understand i detail how it works at a low-level, and how it's wired in the the Arduino environment? I have a few questions, but don't want to explain them if nobody here is familiar enough with the implementation details to answer them.

Me too. I'd like to know more about how it's supposed to be used, rather than the extremely simple description in the Arduino reference.
