How can I use query cursors in Django nonrel on Google App Engine Python?

How can I use a query cursor with Django-Nonrel? If there is no way currently, it would be appreciated to tell me where to look at in Django-Nonrel. http://code.google.com/appengine/docs/python/datastore/queries.html#Query_Cursors

I'm using Paginator from Django, but it's apparently inefficient with large data.

Thanks

djangoappengine supports cursors:

from djangoappengine.db.utils import get_cursor, set_cursor
