@lukastaegert Everything passing except for code coverage. Please add additional tests if you like.

[lukastaegert]

Thanks a lot. Just a note, it will take a while until I can work fully through this.

[kzc]

Test coverage was improved, but was unable to get 100% patch coverage. For whatever reason I couldn't simulate a stdin read error on Node within CircleCI. The same test worked locally on all Node versions. That particular test was commented out in the PR. I don't plan to spend any more time on it.

[kzc]

Just so there's no confusion, this PR works fine. That simulated stdin read error test is just a nice to have. It's not clear to me whether Node actually generates stdin read errors in any circumstance.

[lukastaegert]

Moving this to a local branch as there are still some changes I want to add
