The computer is never really idle. Background processes are always running. Some block sleep, others don't. As a rule, background tasks that are not listening on the network will not block sleep. Use the free application "Caffeine" to prevent sleep while a background task is running.

Well it may be running background processes but the foreground process of video encoding (in this instance) was definitely suspended. Thanks for the heads up on Caffeine, will look into that.

Yes, but we shouldn't have to use a third-party application to keep the system running when there are foreground processes running. This wasn't an issue under Snow Leopard or Lion. And before anyone says this is a Power Nap issue, that only works with SSD based Macs, so on Macs that don't have SSD, I don't know why it wouldn't revert to previous behavior.
