Is this really an issue in Python? The Python interpreter is not thread safe 
anyway, there's a global interpreter lock that must be held by any thread 
accessing Python objects.
Depending on what you're trying to do, this might be one of Python's biggest 
disadvantages, but as far as I can see, you don't need to worry about "true"
concurrency, simply because it can't happen.
