+1, .select() and derivates are, maybe, the most important function and
it's crucial that they must be optimized.
Using them in python is really slow on large datasets.

I would like to have this simple (and optimized) function:

    layer.selectOIDS ( extent ) -> returns an array of OIDS (integer),
fetching only one field

and then I use:

    layer.fetchAttributesByOID ( OID ) -> returns an array of attributes
