28703	URL regex for admin's app_index view isn't constructed deterministically	Erik Bryant	nobody	"https://github.com/django/django/blob/master/django/contrib/admin/sites.py#L277

The regex pattern that is constructed for an endpoint is not stable. For instance, in my project I have seen it construct each of the following:
{{{
^admin/^(?P<app_label>social_django|authtoken|queues|jobs|files|users|clusters|appps|auth|vdcs)/$
^admin/^(?P<app_label>social_django|auth|users|vdcs|appps|jobs|queues|authtoken|clusters|files)/$
^admin/^(?P<app_label>authtoken|appps|social_django|clusters|users|queues|jobs|vdcs|auth|files)/$
^admin/^(?P<app_label>authtoken|appps|social_django|clusters|users|queues|vdcs|jobs|auth|files)/$
}}}
This precludes the use of patterns in unit tests.
