PyV8 testLocker segmentation fault

[GoogleCodeExporter]

After upgrading both V8 and and, it seems like PyV8 test segfaults as shown 
below

Original issue reported on code.google.com by angelo.d...@gmail.com on 21 Jan 2013 at 10:13

[GoogleCodeExporter]

A deeper analysis revealed that the test segfaults while accessing 
JSLocker.locked at line 1755

1752 class TestMultithread(unittest.TestCase):
1753     def testLocker(self):
1754         self.assertFalse(JSLocker.active)
1755         self.assertFalse(JSLocker.locked)

I simply modified the code in order to 'dir' the JSLocker attributes and the 
attribute `locked' seems to exist but every attempt to access it leads to the 
segfault.
