That may still takes n+1 DB hits - remember that the BMP finder returns
a set of keys - beyond that you're OK if the bean is already in cache
(commit option A). If you're doing all this from a session bean (in
transaction) it shouldn't be any faster with a BMP finder than what
you're doing. Unless I'm missing something big.
