I don't think so. The way to screw up generators is to try to set them
backward. Since the amount added to the generator (new.TEST_ID -
GEN_VALUE) is always positive, having two users run it at once shouldn't
be a problem. If new.TEST_ID is less than GEN_VALUE, there's a chance
that it will duplicate an existing key value, but that is the
application's problem.
