Note that in a giant thread on zope3-dev:

http://mail.zope.org/pipermail/zope3-dev/2005-March/013884.html

people are claiming that "obsolete BTrees and intsets" aren't genuine problems.  Since Zope Corp software doesn't use them, we're going to need a much clearer statement of "the problem" from people who _do_ use them if there actually is a problem here.

I added aliases for ZODB.Persistent{Mapping,List}, which will land in 3.3.1 and 3.4.

Tiran, could you subscribe to zodb-dev long enough to discuss this there?  A good start would be replying to Jim's message from yesterday morning:

Some modules or module aliases are missing in Zope 2.8. This breaks existing software and unpickling from ZODB. Here is a list of missing modules I found until know:

* ZODB.PersistentMapping
* ZODB.PersistentList
* BTree
* IOBTree (including aliases like IOBTree.Bucket -> BTrees.IOBTree.IOBucket)
* OIBTree
* intSet

The import of the modules isn't marked deprecated in Zope 2.7. Also I don't see any migration code for existing instances in ZODB. It should be very easy to solve the issue by adding module aliases.
