QtConcurrent errors

bagipro

I have the code
@int countThreads = 3;
for(int i=0;i<countThreads;i++)
{
QFuture<void> future = QtConcurrent::run(this,&MainWindow::thread);
threads.push_back(future);
}@

@void MainWindow::thread()
{
while(lastLink < countLinks)
{
int i = lastLink;
QString req = doRequest(links[i]);
}
}@

@QString MainWindow::doRequest(QString url)
{
QString out;
QTimer timer;
QNetworkAccessManager* manager = new QNetworkAccessManager;
QEventLoop loop;
QObject::connect(&timer,SIGNAL(timeout()),&loop,SLOT(quit()));
QObject::connect(manager,SIGNAL(finished(QNetworkReply*)),&loop,SLOT(quit()));
QNetworkReply* reply = manager->get(QNetworkRequest(QUrl(url)));
timer.start(TIMEOUT);
loop.exec();
if(!timer.isActive())
{
reply->abort();
}
else
{
if(reply->error() == QNetworkReply::NoError)
{
out = static_cast<QString>( reply->readAll() );
}
reply->close();
}
delete manager;
return out;
}@

This code must do requests to links with 3 threads, but it do in 1. (In random moment 3 connection, but not 1)
