4948	Saving FileField files is not thread-safe	anonymous	Robert Coup	"Picking the filename in [http://code.djangoproject.com/browser/django/trunk/django/db/models/base.py#L368 django.db.modes.Model._save_FIELD_file] is not thread-safe. There is an obvious racing condition if one thread will have found a non-existing filename and then a second thread will search for a non-existing name based on the same filename before the first thread starts to write the file.

Because this function is probably most often called from the admin UI and the newforms frameworks doesn't support file upload yet, it isn't critical. Still, this kind of problems can cause difficult to debug problems."		closed	Core (Other)	dev		fixed	fs-rf-docs		Accepted	0	0	0	1	0	0
