lp.services.webapp.tests.test_error.TestDatabaseErrorViews.test_disconnectionerror_view_integration fails intermittently/rarely in parallel tests

[Gary Poster]

Very similar to bug 974617. We should insert some retry code in this test just as we did for test_operationalerror_view_integration in the same file--or better, abstract it.

        retries = 10
        for i in xrange(retries):
            try:
                urllib2.urlopen(url)
            except urllib2.HTTPError as e:
                if e.code != httplib.SERVICE_UNAVAILABLE:
                    raise
            else:
                break
            time.sleep(1)
        else:
            raise TimeoutException(
                "Launchpad did not come up after {0} attempts."
                    .format(retries))

The failure message is over here: http://pastebin.ubuntu.com/1001345/

Seen again, now on 32 thread machine. Maybe we need to further increase the retry for this situation.
