but, on every circ, we want to handle the item update in zebra too right 
? so we will have to :
1- update the item in SQL
2- rebuild the MARC record with biblio+items
3- reindex zebra with both

so won't the gain be very small (gain in step 1, but loss in step 2, 
that is fast with the actual structure) ?
