Conversation
Calling `process.exit()` calls the C `exit()` function, which in turn calls the destructors of static C++ objects. This can lead to race conditions with other concurrently executing threads; disposing of the V8 platform instance helps with this (although it might not be a full solution for all problems of this kind). Fixes: nodejs#24403

Beginning to wonder though … does this interfere with Workers? They might be attempting to access the platform while we are shutting it down here, right? :/ |

Isn't the proper solution to join all threads first? |

If I'm not mistaken, it looks like this doesn't fix test-cli-syntax. https://ci.nodejs.org/job/node-test-commit-linux/23744/nodes=centos7-64-gcc6/testReport/ is a CI run for this PR. assert.js:86
