I've managed to sleep 12+ hours nearly straight through (minus some barely remembered lav runs) on a couple of longer flights; the combination of a 1AM-ish departure and a 14 hour flight on the CX SFO-HKG flight are particularly conducive to it.
Well my experience was on the A345 and A300, and they are warm if not hot.. I guess it also depends on the person..
Yes; I generally run "warm" most of the time though, so it's a bit surprising. It definitely does vary person to person, and also temperatures vary between flights and even between seats (window, which I tend to favor for long flights where I might sleep, trend cooler.)
