I notice that some linalg operations uses make_contiguous_array which may create temporary structs values with its data being weakly owned (i.e. either owned by another NDArray instance or only used for the during of the extern call).

We can stacksave before creating these temporary values, call the extern linalg functions, and stackpop to save some memory.
