Stephen and Toni:

Willian and I were talking about DAG and thinmesh tonight, and I took a 
closer look at the changes this week to Object.c (and then I briefly 
cursed you both for the comment "when we move to tp_getset, the 
individual settors will need to set the flag").  Can you two elaborate a 
little more now on what other modules need to be doing (if anything)?
