The test starts child processes. A recent change is suspected of causing
flaky crashes on one of the alpine buildbots but we can't know for sure
because the test hides the child's stderr.

I propose fast-tracking this.

This causes the test to fail because it changes how stderr is handled so the assertion that checks stderr needs to be adjusted....

/home/iojs/build/workspace/node-test-commit-linux/nodes/debian9-64/test/parallel/test-startup-large-pages.js:25
  assert.strictEqual(child.stderr.toString().match(/\S+/g).slice(1).join(' '),
                                  ^

TypeError: Cannot read property 'toString' of null

Oh pfft, that was the version I tried for reproducing the crash locally (no crash), not what I wanted to PR. Updated, PTAL.
