It's all about the oil temp. If the oil temp is up the engine should be OK. that said letting the car idle will not warm up the transmission fluid, gear oil in the rear end, etc. so better to drive it gently until the oil temp comes up, then go for the redline.

Now a whole 'nother thread could probably be started as to exactly how warm the oil should be before you spin it out...
