Given the discussion on this thread, I think we should implement
isolated worlds in the V8 bindings first, adding the tests to
LayoutTests/http/tests/security/isolatedWorlds.  Once we get that in
reasonable shape, we can work on the JSC implementation.

Currently, isolated worlds is on the critical path to releasing chrome
extensions.  Switching on the feature might break some extensions that
are relying on direct access to the page's JavaScript.  We'd like to
turn the feature on as soon as possible to stabilize the extension
platform prior to release.  There doesn't appear to be a similar
schedule pressure on the JSC implementation.

I want to be clear that I'm not promising to do the JSC implementation
all myself.  I'll certainly help, but the work will be prioritized
with my other WebKit contributions.
