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. 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.

Checked in. See rev 59478.
