Yes, they do pre-allocate, though not in a very smart way.
See the setSizeIncrement() and sizeIncrement() method docs. Essentially they
pre-allocate a constant amount for each insertion (if there isn't enough
room). I usually prefer some sort of exponential pre-allocation but it's
better than nothing.
