I know about this

Hello zodb-dev!
Is this a correct behaviour?
from BTrees.IIBTree import IIBTree
t = IIBTree(map(None,range(5),range(5)))
list(t.keys())
[0, 1, 2, 3, 4]
k = t.keys()
list(k)
[0, 1, 2, 3, 4]
del t[0]
list(k)
[]
BUT
i = iter(t.keys())
del

Nothing is defined about what an iterator sees
