Error/Crash using multiple JSContext in multiple threads about pyv8 HOT 3 CLOSED

I am still able to reproduce this defect. What is its status?

Can't reproduce it with the latest SVN trunk code, but we must enter a isolate 
before use it in a separate thread

from __future__ import with_statement
import PyV8
from threading import Thread

class PyV8Tread(Thread):
    def run(self):
        with PyV8.JSIsolate():
            with PyV8.JSContext() as context:
                context.eval("1+1")

                del context

t1 = PyV8Tread()
t2 = PyV8Tread()
t3 = PyV8Tread()
t1.start()
t2.start()
t3.start()
