Well, there's no difference as far as my task running and my page
updating goes.  However, if I turn on debug logging to watch my SQL
execute, adding the flush() statements to JPAThreadManagerImpl.java
results in the UPDATE roller_tasklock statements being completed with a
COMMIT, rather than a ROLLBACK.  And of course the table now updates as
expected also.

I don't know the codebase well enough to know if I really fixed
everything, but at least it's working better than it was.
