16022	Cyclic reference in FieldFile causes memory usage to grow considerably	Gustavo Narea	Joshua Massover	"django.db.models.fields.files:FieldFile creates a cyclic reference to the model instance it's attached to via django.db.models.fields.files:FileDescriptor.

The effects can be considerable. In our Web site, for example, it causes the process running Django to increase the memory used by over 1MB after every request.

The patch is generated against Django trunk, even though it's only been tested under Django 1.1.4 (but the cyclic reference doesn't seem to have been fixed)."	Cleanup/optimization	assigned	Database layer (models, ORM)	4.0	Normal		memory leak	Ülgen Sarıkavak	Accepted	1	1	1	1	0	0
