Wondering why calling _delObject() in BTreeFolder, which inherits _delObject() from ObjectManager, doesn't work with BTreeFolder._getOb(), and I have to use BTreeFolder._delOb() to delete a contained object in a BTreeFolder. Is this incompatibilty by design? I run into trouble using _delObject (traceback #1 below), getting a deliberately raised AttributeError, but changing this to _delOb raises a key error when calling 'del tree[id]' on line 195. Thoughts?
