Comment:
The fault is in `django/models/query.py:get_cached_row()`: when it
recurses it was not passing the `only_load` dict down the stack. The
attached patch fixes this.
However I noticed that the recursion is not passing anything for the
`offset` parameter, which is to do with aggregation queries. I can't say
for sure at the moment, but it looks to me like an additional bug relating
to aggregated queries with related models could be hiding in here as well.
Or is the `offset` parameter '''only''' relevant to the top-level model?
