As to the playlist write, this mechanism of last-minute writing as power goes down seems to work very well at the moment. How much extra information could be written in the time available?

Only a few bytes get written to NVRAM at power loss time. It basically keeps track of where you were in the current playlist, plus a couple of other little things.

It's doesn't do any disk operations at power loss. For instance, when you begin playing a new shuffled playlist, it writes that into scratch space on the hard disk at the time you begin playing it, not at power down.

At least this is the way I understand it to work.
