[Seaside] transaction engines?

[radoslav hodnicak]

Does anybody happen to know/have an engine that implements transactions
for normal smalltalk objects? No external access or anything needed.

Currently I'm using GLORP and it works well for loading and saving objects
(postgres can massage a lot of data quickly), but having separate glorp
session for every seaside session is biting me more and more often,
especially because the unit of works cannot be nested in glorp. It doesn't
work with forked browser paths too.

I figure having a single glorp session to actually do the wire transfer
should be enough, and I'd do the rest in image alone.
