Seriously (and not knowing the exact meaning of contrived), a good
application is the parent link in a DOM tree. The problem is that this
is 
a) probably a too complex example for the documentation, as just
   making parent weak is not enough - ownerDoc also needs to be weak,
   and,
b) nobody has changed any DOM implementation to make use weak
   references; Fred was asking for a real application.

P.S. I've considered using weakrefs in minidom, but put that plan
aside since that would break portability with 1.5.
