flaky test-regress-GH-814_2 #34527

• Version: 15.0.0-pre (current master branch)
• Platform: fedora-last-latest-x64
• Subsystem: test, fs, libuv

What steps will reproduce the bug?

Run test/pummel/test-regress-GH-814_2.js on fedora-last-latest-x64 in CI.

How often does it reproduce? Is there a required condition?

Not every time. Running https://ci.nodejs.org/job/node-stress-single-test/151/ right now to see how often.

What is the expected behavior?

The test should pass.

What do you see instead?

The test crashes with -9, which I believe means libuv is complaining about a bad file descriptor.

Additional information

Something similar to this was going on with readstream last year and I think @addaleax fixed it. Maybe fs has the same/similar issue, perhaps when explicit fs.close() is not used?
