It seems the version of Python that ships with OS X does not support POLLIN. The versions shipped in Homebrew have it enabled.

This means MacOS targets are broken too. I will re-add support for select.select. Thanks for reporting!

Thank for the fast reply!
I set ansible to use python from the brew and everything works!
Thanks again!
