ChangeLog structure should be:
Web Inspector: <foo>
http:// bug

Detailed description.

...

No need to enumerate all the new methods.

NodesSlive and RetainersSlice can inherit from single class.

I like iterator name better.

reset: function

> Source/WebCore/inspector/front-end/HeapSnapshot.js:82

next: function()

length

hasNext: function()

Should this string be localized?

> Source/WebCore/inspector/front-end/HeapSnapshot.js:221
> +    becomeDominator: function()

ditto to the naming.

please declare named local function above (as sortByNodeField).

After declaring order functions separately above, this no longer applies.
