Comment (by dfeuer):

 Building on Ryan's `StoreImpl` attachment, I've come up with `Store-
 Tuples` and `Store-Random`. `Store-Tuples` is very simple, and
 demonstrates a roughly 50% increase in allocations, but not an increase in
 residency. `Store-Random` is somewhat more involved, and demonstrates
 increases in both (although it's clearly not the biggest culprit). I hope
 these will at least help point toward the problem.
