	Couple of comments on this version:

	1)  You've got an item_get that doesn't have a corresponding  
item_remove (:1113)
	2)  I don't completely understand why item was expanded for an  
identifier.  Its usage seems to suggest it's a parameter being passed  
into store.
	3)  Can no longer distinguish between a missing record (need to add)  
or a missed identifier (need to refetch and try again).

	Both #2 and #3 seem to have something to do with the new parameter  
on item_alloc.  Is it possible to avoid this API change?  It's not a  
*huge* deal, but it causes a forward compatibility issue with my  
binary patches on my single patch stack.  If you could avoid the API  
change, I wouldn't have to maintain two different versions.  :)
