With this patch, setting request.urlconf to None would return a resolver based on settings.ROOT_URLCONF instead of raising an ImproperlyConfigured exception. I have to say that I find this rather elegant and logic. Of course, this should be documented (and the failing test fixed). Opinions?

I agree with Claude, falling back to settings.ROOT_URLCONF is quite elegant and logical. I'll write up a patch for this.

Did you do some performance testing? I'm not sure whether this really impacts performance in a noticeable negative way.
Anyway, applying this patch breaks the testsuite (FAIL: test_urlconf_overridden_with_null (regressiontests.urlpatterns_reverse.tests.RequestURLconfTests)) and breaks assigning request.urlconf:
http://docs.djangoproject.com/en/dev/topics/http/urls/#how-django-processes-a-request
The patch at least needs improvement and probably additional justification too.
