[TIP] pytest xdist raise INTERNALERROR occasionally on Windows 2008r2

[Baiju M]

Hi,

I run tests on Windows 2008r2, the number of tests is 50.  The test fails with
a traceback like this:

INTERNALERROR> Traceback (most recent call last):
...
INTERNALERROR>   File
"e:\functional_tests\eggs\pytest_xdist-1.8-py2.6.egg\xdist\dsession.py",
line 201, in pytest_runtestloop
INTERNALERROR>     self.loop_once()
INTERNALERROR>   File
"e:\functional_tests\eggs\pytest_xdist-1.8-py2.6.egg\xdist\dsession.py",
line 219, in loop_once
INTERNALERROR>     call(**kwargs)
INTERNALERROR>   File
"e:\functional_tests\eggs\pytest_xdist-1.8-py2.6.egg\xdist\dsession.py",
line 272, in slave_collectionfinish
INTERNALERROR>     self.sched.init_distribute()
INTERNALERROR>   File
"e:\functional_tests\eggs\pytest_xdist-1.8-py2.6.egg\xdist\dsession.py",
line 132, in init_distribute
INTERNALERROR>     assert collection == col
INTERNALERROR> AssertionError: assert ['XXXXXXXXXXXXXX', ...] ==
['XXXXXXXXXXXXXX', ...]

That 'XXXXXXXXXXXXXX' (masked) is same in left and right whatever displayed.

I have pasted the full traceback (masked the actual test) here:
https://gist.github.com/3432544
This doesn't happen always.  The test is invoked from Jenkins.  pytest
version 2.2.3

Let me know, if any other details required.
