No can do. I have some sort of corruption in the ODB that becomes apparent
when I try upgrading (see trace below). On top of this I don't want to drag
around the history of everything else in the ZODB. How hard would a
selective pack operation be? ie pack everything but one folder

hmm, sounds complicated. Actually sounds like ZODBReplication or
synchronization. Can you outline in a little more detail how you would do
this? How do you tweak the modification time etc?
