17951	Limit items in ModelChoiceField by default	Dan Poirier	nobody	"I suggest that above some default number of items, a !ModelChoiceField should automatically switch to raw_id_fields mode.  There could be a new parameter to change or remove the limit.

I've seen a couple of instances lately where a new Django admin page mysteriously would not load, with CPU pegged, and it turned out the model being admin'ed had a !ForeignKey to a table with millions of entries, which turned into a !ModelChoiceField in the admin that tried to build a widget with millions of items... it didn't work very well.  This was the default behavior, not a result of deliberately choosing to create a ModelChoiceField on that big table."	New feature	closed	contrib.admin	1.3	Normal	wontfix			Unreviewed	0	0	0	0	0	0
