It seems to be running much better now. A word to the wise to people who might encounter the same problem: note that the manual says to change the annotation on your entity manager from @PersistenceContext to @In(create=true) when using Seam-managed transactions and don't forget to change them all, taking care that their names match. The magic of bijection takes a little getting used to. :-) Thank you to Gavin and Justin for their assistance.
