Comment 10 for bug 1017990

For added fun, the code we want to encourage using (open-ils.circ.holds.test_and_create[.batch]) calls the code we want to deprecate (open-ils.circ.holds.create[.override]) internally. (Code re-use, FTW). If we deprecate open-ils.circ.holds.create[.override], we'll need to retain its code in a non-published API / utility function.
