Updating links doesn't always remove FK constraint

[jamoore]

In pseudocode:

   link = obtainLink();
   old_child = link.child;

   link.parent = new Something( link.parent.id, false );
   link.child = new Otherthing( );
   iupdate.saveObject(link);

   // The following *sometimes* throws a ValidationException
   // because the link still points at the old_child
   iupdate.deleteObject(old_child);

I highly doubt this is still a problem, otherwise we would see these validation exceptions coming through. Closing without trying to reproduce something that happens "sometimes".
