5161	mysql backend repeatedly adds warnings filter	adurdin@…	nobody	"See `/trunk/django/db/backends/mysql/base.py`, line 82 (r5609 at time of writing).

The mysql backend's `cursor()` method calls `warnings.filterwarnings()` each time a cursor is requested (if DEBUG==True).  Instead, filterwarnings() should only be called once (e.g. at module load), to avoid needlessly adding identical filters to the warnings module's internal list."		closed	Uncategorized	dev		fixed			Accepted	1	0	0	0	0	0
