Repository: node
Issue: Deadlock at process shutdown
Labels: confirmed-bug,help wanted,v8 engine

### Version

v23.0.0-pre

### Platform

```text
Linux USR-PC2HD4AD 5.15.153.1-microsoft-standard-WSL2 #1 SMP Fri Mar 29 23:14:13 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
```


### Subsystem

_No response_

### What steps will reproduce the bug?

There is a deadlock that prevents the Node.js process from exiting. The issue is causing a lot (all?) of timeout failures in our CI. It can be reproduced by running a test in parallel with our `test.py` tool, for example

```
$ ./tools/test.py --repeat=10000 test/parallel/test-http2-large-write-multiple-requests.js
```

- https://github.com/nodejs/node/pull/52959#issuecomment-2108711217

### How often does it reproduce? Is there a required condition?

Rarely, but often enough to be a serious issue for CI.

### What is the expected behavior? Why is that the expected behavior?

The process exits.

### What do you see instead?

The process does not exit.

### Additional information

Attaching `gdb` to two of the hanging processes obtained from the command above, produces the following outputs:
