This is CI result for running this test 500 times on each platform - https://ci.nodejs.org/job/node-stress-single-test/949/ There are failures on PI platforms, but I doubt they are caused by this change. Please take another look. |
Stress tests uncovered 2 race conditions, when IO events happened during V8 entering event loop on pause or during Node.js shutdown. Fixes: #8669

I have reworked this patch a bit. I got rid of the second mutex, slightly renamed variables and extracted blocks into properly named functions. Please take another look. CI: https://ci.nodejs.org/job/node-test-pull-request/4224/ |

lgtm! |

Thank you for the review. Last CI: https://ci.nodejs.org/job/node-test-pull-request/4224/ |
