I've been seeing this with large atlas exports too. I can reproduce in 2.8, in 2.10 it was much worse, but in master it's back to 2.8 levels. Tried everything I can to track this down with no luck. My suspicion at the moment is a leak in either qt or geos. I'd be interested to see if geos 3.5 has any effect...
