http://trac.webkit.org/changeset/82500 might have broken Leopard Intel Debug (Tests) and Windows 7 Release (Tests)
The following tests are not passing:
fast/dom/Window/window-postmessage-clone.html
fast/workers/shared-worker-frame-lifecycle.html
fast/workers/worker-close-more.html
inspector/debugger/debugger-breakpoints-not-activated-on-reload.html
inspector/debugger/scripts-panel.html

Rolled out in r82519 as someone deemed it reasonable to break DRT so i couldn't fix in trunk fast enough

Hard to tell just by looking if this is correct, but if the tests pass, it look generally OK.

> +            if (m_prototype)
> +                markStack.append(&m_prototype);

Just noticed this, although it's not new in your patch:

It would be nice to get rid of the concept of a JSValue() prototype, and use jsNull() instead, to get rid of this branch.
