Test flake: timed out trying to delete namespace; no pods remaining

Seen here:
https://ci.openshift.redhat.com/jenkins/job/test_pull_requests_origin_conformance/5444

Looks related to namespace deletion with pods remaining, but in this case, it appears to call delete on a namespace multiple times.

/data/src/github.com/openshift/origin/vendor/k8s.io/kubernetes/test/e2e/framework/framework.go:133
Aug 19 14:05:15.574: Couldn't delete ns "extended-test-cli-deployment-m35u7-4doth": Operation cannot be fulfilled on namespaces "extended-test-cli-deployment-m35u7-4doth": The system is ensuring all content is removed from this namespace.  Upon completion, this namespace will automatically be purged by the system.

The test passes but the namespace fails to be removed - this is not deployment-related

@deads2k thoughts?

Agree. @derekwaynecarr probably knows more about it than the rest of us.
