+ Remove "multi-threaded" logic in V8 DOMData, DOMDataStore and friends
+ This functionality is untested and unused:
+ This is an old code from Lockers-based implementation of WebWorkers in
+ V8 bindings, to make sure that DOM objects are released on the right thread
+ even though GC could have happened on any thread. It is currently unused (since
+ current model is one worker per process) and is being removed because new implementation
+ of WebWorkers will be using V8 isolates.
