I used to get hot pixels from jpg shooting but have never seen one when shooting in RAW in LR. I've assumed LR sorts it out on conversion. I refuse to believe my 5d2 is impervious to it but I've never seen one in nearly two years of relentless night shooting.

Seems like it would be better if the camera contained a series of profiles indexed by sensor temperature, with each profile generated from the average of a few thousand consecutive 30-second black shots. Averaged over a large enough number of black shots, random noise should converge towards zero and static noise should converge towards a particular value.
I have noticed weird things like hot pixels one night, in a series of shots; and lack of them or hot pixels somewhere else later the same night or the next evening.
