4050	django/db/models/base.py uses inefficient subclass check	Ludvig Ericson <ludvig.ericson@…>	Adrian Holovaty	"django/db/models/base.py uses
{{{
    filter(lambda b: issubclass(b, Model), bases)
}}}

The supplied patch provides a more efficient version."		closed	Database layer (models, ORM)	dev		wontfix	issubclass models base.py		Unreviewed	1	0	0	1	0	0
