>>> import ZODB
>>> from ZODB.PersistentMapping import PersistentMapping
>>> from BTrees.OOBTree import OOBTree

works
>>> d1 = OOBTree()
>>> d1[1] = 1
>>> pm = PersistentMapping({2:2})
>>> d = {1:1}
>>> bt = OOBTree({3:3})
>>> bt.update(d)
>>> pm.update(bt)
>>> dict(bt)
{1: 1, 3: 3}

But not works
>>> OOBTree(pm)
Traceback (most recent call last):
  File "<pyshell#12>", line 1, in ?
    OOBTree(pm)
  File "C:\Python23\Lib\UserDict.py", line 14, in __getitem__

KeyError: 0
>>> bt.update(pm)
