"A".join(["Bob"]*100)): 0.92 => 2.11

I just optimized PyUnicode_Join() for such dummy benchmark. It's now 1.2x slower instead of 2.3x slower on this dummy benchmark.

With longer ASCII strings, Python 3.3 is now 2x (narrow 3.2) or 4x (wide 3.2) faster than Python 3.2. For example with this micro-benchmark:

./python -m timeit 'x=["x"*500]*5000; y="\n"; z=y.join' 'z(x)'
