It does one query per object received, instead of just one for the entire
batch. Attached is a patch which fixes this. It's technically not
backwards compatible because signals are no longer sent, however one could
artificially send them. Also, in the event of an error, none of the
objects will be modified, whereas currently some of them will be.
