[Numpy-discussion] Appending data to a big ndarray

I would like to build a big ndarray by adding rows progressively. 

I considered the following functions : append, concatenate, vstack and the like.
It appears to me that they all create a new array (which requires twice the memory).

Is there a method for just adding a row to a ndarray without duplicating the data ?
