> Thanks for review. How about removing the API thread lock/unlock for the VM which has an exclusive thread? For example, WK2 is using JSC APIs within the injected bundle, which runs in the WebCore's exclusive VM. I believe it is thread safety when executing JSC APIs in the WebCore's VM.  

I think a specialized design like that would need a more real-world benchmark to justify itself.

There are lots of opportunities for optimizing JSLock.
