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)'
