Change 14161
-Added staged option for ThreadManager and corresponding unit test
-Added operator[] and getOrInsert() in HashMap. getOrInsert() doesn't follow standard but it's consistent with the rest of the HashMap interface; I'll change them when I go back and redo that interface to fit the style.
