-Re: reuse same Tuple and ArrayList for every getNext call in LoadFunc?
I looked into this a while back -- trouble comes when something
downstream from the loader tries to collect inputs into a bag, and
doesn't do its own copies. One can easily argue that if someone wants
to do such collection, it should be their responsibility to ensure
they aren't just collecting the same object that keeps being
overwritten, but at this point, I think it's too late to convert
everyone who might be making the "each tuple is a new tuple"
