I think it makes sense. I think you could verify by replacing the use of os.availableParallelism() in the test runner code with 1 or 2 and seeing if the test hangs.

await fs.writeFile(path.resolve(tmpdir.path, 'test-runner-concurrency'), '');
const { code, stderr } = await common.spawnPromisified(process.execPath, [
'--test',
fixtures.path('test-runner', 'concurrency', 'a.mjs'),
fixtures.path('test-runner', 'concurrency', 'b.mjs'),
]);
assert.strictEqual(stderr, '');
assert.strictEqual(code, 0);
});
