Parallel requests causes losing some stdout

[Brikaa]

Adding a 0 ms sleep here seems to fix it for some reason:

proc.on('exit', async (code, signal) => {
    await new Promise(resolve => set_timeout(resolve, 0));
    this.exit_cleanup();

    resolve({ stdout, stderr, code, signal, output });
});

Commenting the cleanup doesn't fix it

Fixed with the backport PR #613
