Thanks, Karl -- this has been discussed twice in the past two years, in
depth.

I wrote the thing up in the wiki, which is down.*

On long downhills, when your foot is off the gas and with the transmission
in gear so the engine is being overrun, the ECU cuts off all fuel
delivery. The pistons go up and down, sucking in and expelling cold air,
but with no fuel to burn, the engine will go dead cold.
