线程中的PyV8 - 如何使其工作？

Question

Using PyV8 in the main program is ok.
But even if I run it in 1 thread (not main program itself, but 1 additional thread in it)

class TaskThread(threading.Thread):
    def __init__(self, task):
        threading.Thread.__init__(self)
        self.task = task

    def run(self):
        try:
            self.task.run()
        except Exception as e:
            pass

a single line self.task.run() which has this code:

context = PyV8.JSContext(self.window)     # <- this stops everything

freezes the whole program.

I already understood that PyV8 "doesn't like" threads, but still how can I use it for threaded tasks?

I think I found a solution while looking in http://code.google.com/p/pyv8/source/browse/trunk/PyV8.py

If you start thread like:

t = YourThreadClass()
t.daemon = True
t.start()

just start it in this way:

with PyV8.JSLocker():
    t.start()

when you need to run javascript:

with PyV8.JSLocker():
    self.context.enter()
    print self.context.eval('1+1')
    self.context.leave()

Looks like it solves the problem.
