PyArray_FromDimsAndData: Numeric interface to PyCObject data

Hello,

For integrating some codes I try to use PyCObjects with Numeric
interfaces. I have PyCObjects that contain several arrays. I want to
provide these arrays to Python as Numeric arrays using
PyArray_FromDimsAndData, the arrays could grow quite large, so I want
to handle arround references, not copies. Of course this is
dangerous. If I destroy the PyCObject and try to access the Numeric
array referencing its data later, who knows what happens. It would be
nice to have some callback function slot to allow to increase the
refcount of the PyCObject when a Numeric array with a reference is
created and to decrease it when the array is deleted. Is there a way
to achive this. 

Further after skimming over the numarray documentation it seems
PyArray_FromDimsAndData and similar functions for numarray are copiing
the data instead of using a reference. Is this true? If yes, is it
planned to provide a method for generating numarray arrays using
references only?

Kind regards
