Assigned to me.  This was fixed in Zope3/ZODB4 as a side effect of generalizing BTree constructors to play nice with Python 2.2's new iterator protocol.  The Zope2/ZODB3 code is clearly wrong in this case.

In the Zope 3 version, I get this:

 >>> from zodb.btrees.OIBTree import OIBTree
 >>> OIBTree({'x':1.2})
 Traceback (most recent call last):
   File "<stdin>", line 1, in ?
 TypeError: expected integer value
 >>>

from BTrees.OIBTree import OIBTree
print OIBTree( {'a': 1.0} )

raises TypeError, "Sequence must contain 2-item tuples"

The explanation is wrong since this exception is raised by passing a float instead of an int.
