I copied that directly from the net docs for the same feature.

This doesn’t land cleanly on 8.x; if you can, please follow the guide and raise a backport PR, if you don’t think it’s worth it just add the dont-land-on label.

Will break YAML parsing!

Then I extracted out the problematic YAML, and tried running through Ruby as a
separate `.yml` file:

Ping @cjihrig ... Initial basic attempts to backport this for v8.x are failing due to some issue with dns. Will investigate further shortly.

@jasnell not sure. The commit in this PR lands cleanly for me on v8.x-staging. I ran the test suite locally and only saw one unrelated failure (test/sequential/test-benchmark-http.js).

It's likely that the commits I landed today unblocked it. I'll try again tomorrow
