[Twisted-Python] Spurious failure on winxp32-py2.7

[Adi Roiban]

While running tests I see that the following tests fails randomly...
it it was failing  from some time


twisted.words.test.test_xpath.XPathTests.test_position
===============================================================================
[FAIL]
Traceback (most recent call last):
  File "C:\buildslave\twisted\winxp32-py2.7\Twisted\twisted\trial\_dist\test\test_disttrial.py",
line 371, in test_runUntilFailure
    self.assertEqual(5, len(called))
  File "C:\buildslave\twisted\winxp32-py2.7\Twisted\twisted\trial\_synctest.py",
line 447, in assertEqual
    % (msg, pformat(first), pformat(second)))
twisted.trial.unittest.FailTest: not equal:
a = 5
b = 2

----------

On my local computer (Ubuntu 14.04) the test is always skipped.

Does anyone has any idea why the test is not skipped ?

I would like to have stable results from this tests as with the
current state I always have to double check if a failure on XP is a
new one or is just this bad tests.

Thanks!
