Sigh. It didn't work. If I had thought before trying I would have realized it couldn't. I imagine that the container has its own transaction for the queue, which is timing out because the onMessage() method is taking a long time, even though *my* transaction has a longer time out. I think I'm going to just spawn a thread in the onMessage() to handle the work, and return immediately. I lose all opportunity for resends, but c'est la vie.
