# retrieve and update objects for testing updates
# this set (04, 05, ...) test updates to some objects to prove that we're not 
# storing extraneous objects 
#   like 'thaw' test. scheme is to create a 'matrix' of objects that point to
#   each other. update some and put the updated objects back. show that objects
#   not put remain unchanged
#   at end, make sure there's only one copy of each object.
