Oh, boy. I tried to avoid this be doing:
Iterator it = new HashSet(objects.values()).iterator();
However, it looks like the constructor for the HashSet uses an
Iterator, and that's where it's failing. I'll try a clone or something
instead. I want to avoid synchronizing the whole mess, since the DB pool
will be seeing heavy use...
