Description: test_multiprocessing fails with python3. Works with python2.
See http://bugs.python.org/issue3770

Attempted utilization results in error:

Traceback (most recent call last):
File "/usr/lib/python3.1/multiprocessing/synchronize.py", line 28, in <module>
from _multiprocessing import SemLock
ImportError: cannot import name SemLock

During handling of the above exception, another exception occurred:

ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.



Additional info:
* package version(s)
python3 --version
Python 3.1.2

python2 --version
Python 2.6.5


Steps to reproduce:
>> sudo pacman -S python3
>> python3
>> import multiprocessing
>> multiprocessing.Pool(None)
