Uhm, this shows what I wrote in another mail about what ObjectManager 
does is very wrong, I should have looked at the source.

Can anybody explain why manage_delObjects in ObjectManager uses this 
code to delete objects:

while ids:
   id=ids[-1]
   v=self._getOb(id, self)
   if v is self:
     raise 'BadRequest', '%s does not exist' % escape(ids[-1])
   self._delObject(id)
   del ids[-1]

instead of just using a "for id in ids:" loop?

Just curios.
