In SchoolTool, we have sets of first-class persistent objects.  The sets 
store first-class persistent objects in an IOBTree, keyed on the 
object's _p_oid.  However, the implementation details are hidden from 
the application.

Of course, this set considers equality by "persistent identity", and so 
it works differently than a regular python set that uses __eq__ or __cmp__.
