Brilliant, thanks. Final question: Am I correct in assuming the kernel will clean up and rescind an assertion created using IOPMAssertionCreateWithName() if my process exits abnormally (or crashes)?
And the answer is in another IOPMAssertionCreate() search result ;-)
Assertions should be released with IOPMAssertionRelease. However, even if not properly released, assertions will be automatically released when the process exits, dies, or crashes. A crashed process will not prevent idle sleep indefinitely. http://developer.apple.com/mac/library/qa/qa2004/qa1340.html

I'm scratching my head trying to think why I couldn't find that technical note during my searches, and I now realize I was searching for IOPMAssertionCreateWithName not IOPMAssertionCreate. I'll file a report to request that the documentation be updated now that IOPMAssertionCreate is deprecated. -- James Bucanek
