Here is an example that occurred this morning. We use the Google-
supplied Django 1.0, and are using r91 of
http://code.google.com/p/google-app-engine-django/,
which presumably is a reasonably common App Engine / Django
deployment. The request that caused this exception was pegged at
28956ms.

The request has not even reached any of our application code (I
realize that appengine_django is part of our code, but hopefully it is
a lightweight initialization), so I'm not certain how we could
optimize any further.
Looking at this particular trace is misleading; I have lots of
examples of other arbitrary places within this appengine_django/django
initialization where the DeadlineExceededError occurs.
Finally, when we _do_ get a properly inflated application instance
(which we do most of the time), it is blazing fast.
