I suspect that it's not a problem with the python object sticking 
around, but with the underlying memory. Are you quite sure you're not 
mallocing something you're not freeing?

Sorry, I've deleted your original post, but are you passing in a data 
pointer to PyArray_NewFromDescr() or PyArray_New() ? if so, then you to 
free that memory in your own code.

Anyway, perhaps you could post your array creation code again, and 
someone will see something (or just use cython!)
