Ok, here are some numbers

using 1.3.27:

$ time python hugemod_runme.py
real    0m10.648s
user    0m10.374s
sys     0m0.233s

and using 1.3.27 with -modern:

time python hugemod_runme.py
real    0m9.138s
user    0m8.740s
sys     0m0.216s


and using 1.3.28:

$ time python hugemod_runme.py
real    0m8.491s
user    0m8.247s
sys     0m0.209s

and using 1.3.28 with -O option:

$ time python hugemod_runme.py
real    0m7.190s
user    0m6.930s
sys     0m0.208s
