If we reduce the loop to 100, does this test can still detect bug #43699?

[theanarkh]

I think it is ok, this is the original code that trigger the bug.

const { Worker, isMainThread } = require('worker_threads');
const vm = require('vm')

if (isMainThread) {
    for (let i = 0; i < 2; i++) {
        new Worker(__filename);
    }
} else {
    const ctx = vm.createContext({});
    let count = 0;
    setInterval(() => {
        console.log(count++);
        vm.runInContext('console.log(1)', ctx, { breakOnSigint: true });
    }, 0)
}

Running it and it will crash soon.

I confirm that #43699 is still reproducible after this change.

Do you mean #43780 can not fix #43699 ?
