New submission from Philipp Hagemeister:
On my system, {} has become significantly slower in 3.3:
$ python3.2 -m timeit -n 1000000 '{}'
1000000 loops, best of 3: 0.0314 usec per loop
$ python3.3 -m timeit -n 1000000 '{}'
1000000 loops, best of 3: 0.0892 usec per loop
$ hg id -i
ee7b713fec71+
$ ./python -m timeit -n 1000000 '{}'
1000000 loops, best of 3: 0.0976 usec per loop
Is this because of the dict randomization?
