Hi all,

Could you try this issue with the last version of Python 3.6, 3.7 and 3.8a because I think to have fixed the issue on OSX with this PR (https://github.com/python/cpython/pull/1705).

I have an other PR for 2.7, but this one is not yet ready 😕

Thank you for your feedback.

Looks like this isn’t going to get fixed upstream anytime soon. Anyone know the latest status?
