This change makes no sense.  The function on DOMWrapperWorld only returns an isolated world.  It does that for performance.  This leads to semantic ambiguity like in V8GCController::minorGCPrologue:

        DOMWrapperWorld* world = worldForEnteredContextWithoutContextCheck();
        if (world && world->isMainWorld()) {

the branch will never be taken and minor gc is disabled because of this.

Please consider this reverting this renaming.

[Kentaro Hara]

ah... This was a big mistake. Let me revert them.

Because we're limiting the number of nodes handled by each minor GC to 10000, I couldn't detect the performance regression by Dromaeo/dom-modify...
