Re: Queryset cloning is very expensive

I found a solution which is suitable for me.
As it turns out, all those methods just clone queryset, and then call
appropriate methods of Query object.
So, for example, to set ordering and to get a slice without cloning
queryset, I can do the following:

qs.query.add_ordering('-created')
qs.query.set_limits(high=10)

Note you are now using a Django-internal API that is not guaranteed to be stable (see http://docs.djangoproject.com/en/1.2/misc/api-stability/). Your code could very well break in some future version of Django.
