*x is not deleted since you used PyArray_SimpleNewFromData; that *x is a 
global is irrelevant here.

In the code you posted this time, incref() is required so that someone owns a 
reference to the array object. What I don't know off the top of my head is 
whether you need an incref in the constructor of A and a decref in the 
destructor of A.
