Yup, checkbtrees.py does a *breadth* first search from the root object, so
it naturally lists reachable objects in increasing (well, non-decreasing)
length of access path from the root object.  So it's not an accident that
objects got clumped according to length, but it's not terribly useful either
<wink>.
