Investigate flaky test-vm-sigint #7767

Description

@Trott

From time to time, test-vm-sigint.js fails on CI with no indication of what went wrong.

https://ci.nodejs.org/job/node-test-commit-linux/4202/nodes=centos5-32/console:

not ok 1066 parallel/test-vm-sigint
  ---
  duration_ms: 0.348

It's not timing out, but there's no assertion error either. It's just exiting with a bad code, I think?

    fwiw, after you pinged me the first time on it, I ran the test with --repeat=100000 and it came back clean for me… any tips on how to get closer to the CI environment?

    Also… would segfaults or similar conditions present that way in the CI output?

    Alas, not sure how to repeat it. I think segfaults would show up in the CI output, but... uh... /cc @nodejs/build on both questions, I guess. @nodejs/testing too?

    Another today, this time on 64-bit CentOS 5.

    https://ci.nodejs.org/job/node-test-commit-linux/4390/nodes=centos5-64/console:

    not ok 1071 parallel/test-vm-sigint

    Now that there's code added to print the signal, it fails like this:

    not ok 1072 parallel/test-vm-sigint
    # CRASHED (Signal: 12)
    

    https://ci.nodejs.org/job/node-test-commit-linux/4427/nodes=centos5-64/console
