Actually, I'm not sure this is absolutely necessary -- life is tough, 
especially if you are programming in parallel, and there are limits to 
hand-holding.

However, an explicit declaration could be added for turning the error off 
for the (rare) cases where this makes sense (e.g. setting a shared flag)

	cdef cython.parallel.shared[double] some_flag
