PicklingError when using cotyledon on win64 about cotyledon

[jdandrea]

Whoops, I'm now at a loss as to how the case was cracked (and why on earth nothing was mentioned herein). I will go ISO answers and, hopefully, report back.

To support windows all objects passed to children process must support Pickle. Your application seems the pass some argparse objects to children. More generally master process should do a very minimal works.

I 'm guessing identity is this one: https://github.com/python/cpython/blob/master/Lib/argparse.py#L1638

Thank you! I did a search for argparse in my project and only one component uses it: pbr. I think I will ask them about it or see if anyone has filed an issue.

@jdandrea how to solve this problem on win64?

[jdandrea]

@jacobluo A patch has merged for pbr that I hope resolves this issue.
