I recently got interested in multiprocessing computation with numpy and 
now I get scare by your statement !
Please don't tell me it is unsafe to launch multiple jobs (for instance 
with multiprocressing's Pool.map) just doing some ndarray arithmetic !

That's why I'd like to understand better the issue raised by Yang. For 
instance, what does exactly "multiple CPython interpreters" stands for ?

Best,
Pierre
