[Zope] CST, non-undoing Berkeley Storage, and Versions

[Chris McDonough]

I think the answer depends on which storage you're using to hold the
external data container, and might be "dont use that storage".

I actually have a suspicion that CST has nothing to do with it, and that
if the mounted external database was (for example) a FileStorage, that
this error might never happen.

But that poses a problem, because to my knowledge, there are no
version-aware but non-unoing storages, of course.

Sigh.  The answer is... "not practically", I believe.
