Look the inconsistent behavior:
$ ls
modulo_c.pyc  modulo_o.pyo
$ zip modulos.zip modulo_o.pyo modulo_c.pyc
  adding: modulo_o.pyo (deflated 38%)
  adding: modulo_c.pyc (deflated 38%)
$ ls
modulo_c.pyc  modulo_o.pyo  modulos.zip

$ python2.4
>>> import modulo_c
modulo_c
>>> import modulo_o
ImportError: No module named modulo_o

$ python2.4 -O
>>> import modulo_c
ImportError: No module named modulo_c
>>> import modulo_o
modulo_o

$ rm *.pyc *.pyo
$ ls
modulos.zip
$ PYTHONPATH=modulos.zip python2.4
>>> import modulo_c
modulo_c
>>> import modulo_o
modulo_o
$ PYTHONPATH=modulos.zip python2.4 -O
>>> import modulo_c
modulo_c
>>> import modulo_o
modulo_o

The discussion on python-dev (both last year's and this
year's) has shown that this is the wrong way of fixing the
inconsistency. Instead, zipfile should stop importing .pyo
files when -O isn't given. Rejecting the patch as invalid.
