LGTM, thanks!

File src/runtime.cc (right):

http://codereview.chromium.org/6606002/diff/1/src/runtime.cc#newcode11317
src/runtime.cc:11317: HandleScope scope;
It's not performance critical, but just for consistency please use "HandleScope
scope(isolate)" in runtime.cc.

src/ast.cc:255: Handle<Object> key_handle = FACTORY->NewNumberFromUint(hash);
Given the number of FACTORY usages here it might make sense to cache it.

Turns out Dmitry has a change with 100 additional revisions. I'll abandon this
