Multiprocessing error on Python 2.7 and Windows

[JayZar21]

I tested green on Linux and I had no issue. I used green for testing the same code base on Windows and I had issues with the multiprocessing module (forking):

>green -s 1

It seems to be an issue of python which is not backported. However I use python 2.7.10 (the latest) and a workaround would be appreciated!

If you're using python < 2.7.11, it might caused by this bug: https://bugs.python.org/issue10128

This is how did i run nosetests for mutliprocessing with python < 2.7.11, you may try to crate one for green. from nose import main if __name__ == '__main__': main()

@JayZar21 Sorry about the huge delay. Are you still affected by this issue? If so, will you please provide some code that causes the issue?

[CleanCut]

If this still affects you and you can provide some way for us to duplicate the problem, please reopen this issue.

Sorry, I'm late. I have just tested: this issue seems to be solved. I have other problems with unicode... but this is another story and I have to verify my issues!! Thank you!

[CleanCut]

Okay. Make sure to test the latest version -- we had some windows unicode fixes in the last release.
