I've been unable to reproduce the hanging behavior with apache configured in a variety of different proxy configurations and beating on it for quite a while. I have verified that the version in hardy-proposed, 2.2.8-1ubuntu0.9, also functions when configured to proxy, as well as continuing to serve webpages under load. I also ran the security team's regression test for apache and found no regressions there.
