There is probably something on the port object we can't pickle. It's hard for me to fix this without a Windows machine, it's probably pretty straight forward, though (we had a similar problem with the helper object)

I've done this in the past with something like this:

def find_non_pickleable(obj):
    for name, value in obj.__dict__.items():
        try:
            pickle.dumps(obj)
        except pickle.PicklingError:
            print('{} is not pickleable'.format(name))
            find_non_pickleable(obj)

Actually, Sam Sneddon said they might have a partial fix for this somewhere
