Passing an interable to the __init__ method of an existing deque
appends those elements, rather than reinitializing the deque with the
items. This is contrary to how list.__init__ works.

test_deque.py verifies the (possibly) incorrect behavior.

I agree, I put the list behavior in on purpose.

Should be fixed in 2.6, not 2.5 though, since it's a feature.
