Tentative LGTM. 

Would appreciate another pair of eyes as the storing of iterators makes me slightly nervous... I'm not sure what the invalidation rules are for instruction's iterators off the top of my head. I couldn't find the answer confirmed in any docs either (perhaps I didn't look hard enough?).
