I still maintain my belief that, it'* idling like that to protect the engine incase a few things go wrong. It'* harder to kill, keeps oil pressure up on cold starts, and helps warm up the engine. Any extended idling past an open loop is pointless, and can only cause uneccessary wear.
The point is that it'll do it indefinitely. The temp guage can be at 195 degrees and it'* still racing at 1500 RPMs...for no reason.
I can understand it reving when cold to protect the engine. But when it'* been running for 15 minutes, warmed up and sitting at 1500 RPMs, I'm not convinced that'* normal.
