Line like this really seem to confuse the "BTrees" package.
For us, they can raise a "KeyError" (reported today in the
"zope-dev" and "zodb-dev" mailing lists).

We have successfully replaced the "BTrees" package in our
development environment by that from ZODB 3.2a1.
On Sunday, we will go into production.
I will report whether our problems go away with the new
"BTrees" package.
