The problem here are not the subclasses of OM, but all objects that are
supposed to be added to an objectManager. There is no other method in
the OM class to add an object to an OM instance so it's obviously not a
"private" method (in the "others shouldn't be calling it" sense). All
objects that are designed to be added to an OM instance call it either
in their __init__ or in a factory function (like manage_addSomething())

Let's not confuse this with TTW public methods. _setObject should
obviously not be made TTW accessible (let alone TTW public :-), but it
should be a "public" method, that is, have a sensible name and be
specified in an eventual IObjectManager interface
