To be clear, I'm interested in how the _p_jar happens on a new object
that's just been created. Basically if you do:

If that's a concern, maybe it can be called order__ or something ? What's

For the ConflictErrors, you'll have to isolate what objects they apply to

this list 1-2 months ago to get more information off ReadConflictErrors to

For the ZEO server I don't see the point of changing it, it works well.
OTOH a ClientStorage has to integrate with the other servers in Zope,
and that's the one that would benefit from being moved to the twisted
event loop if twisted is used.

You don't need any transactions to at least test this sequence, only the
Persistent base class and a dummy connection can be involved.
To really test the history yes of course you'll need a full database. Many
