The issue is that in the end, it only needs a String array the size of String[UniqueTerms] - but because it can't easily figure out that number, it first creates an array of String[MaxDoc+1] - so with a ton of docs and a few uniques, you get a temp boost in the RAM reqs until it sizes it down. A pointer for each doc.
