r=me, though I assume this requires the changes the to Deque first.

These are the three remaining clients:

    1) CSSMutableStyleDeclaration::m_values -- can be a Vector, I think
    2) Document::m_windowEventListeners -- Vector? ListHashSet?
    3) EventTargetNode::m_regdListeners  -- Vector? ListHashSet?

I think that CSSMutableStyleDeclaration might be a great candidate for ListHashMap, something like

ListHashMap<int, CSSProperty>

(the item accessor will be O(n), but that is already the case)

Clever!

I prefer listeners->at(i).

Same thing here.

I think RegistereEventListenerVector is better here.
  
r=me!

I usually delete the files in a separate commit. Boy it feels great to see those red patches on webkit-changes ;)
