Thanks to everyone for the suggestions so far. Alas, pmset -g it doesn't show any active assertions (I know it can do as I slapped one in my code and it showed up). I have also tried turning off ttyskeepawake, but to no avail. I didn't mention in my previous email that I have no problem with display sleep working correctly, its just idle sleep that is misbehaving. Looking through the logs, I can't see any power related ones. Apart from user interactions, what other sorts of activity automatically prevent idle sleep?
