POSIX semaphores need /dev/shm to work. Without this, python
multiprocessing gives errors:
```
Traceback (most recent call last):
...
File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 75, in __init__
sl = self._semlock = _multiprocessing.SemLock(kind, value, maxvalue)
OSError: [Errno 13] Permission denied
```
