9849	select_related in admin change_list	krylatij	nobody	"
When ForeignKey field appears in list_display django 
automaticaly executes select_related() for my model. 
So in my case it generates query with about 17 joins.  =(
It will be great to manage which fields to query.

So it's pretty easy to fix without backward incompatibility changes.
As i understand you need to change only django\contrib\admin\views\main.py and django\contrib\admin\validation.py
