17787	Clear setting-dependant caches when settings are overridden (in tests)	Aymeric Augustin	Claude Paroz	"r16237 introduced a `setting_changed` signal, triggered by the `override_settings` decorator / context manager.

However, Django doesn't use this signal to reset caches that depend on built-in settings. In the current state of thing, the signal is only usable is third-party code.

Is this a design choice or a bug?

Marking as release blocker since it's a major bug in a new feature."	Bug	closed	Testing framework	1.4-beta-1	Release blocker	fixed			Accepted	1	0	0	0	0	0
