[webkit-help] How to clear memory held by QtWebkit?

[Bono Damodi]

Hello,
is there a way to deinitialise QtWebkit in runtime completely? For example
for this code:

#include <QApplication>
#include <QGraphicsWebView>
#include <QUrl>
#include <QTimer>

QGraphicsWebView* graphicsWebView;

class Deleter : public QObject
{
    Q_OBJECT
public slots:
    void deleteWebView()
    {
        delete graphicsWebView;
    }
};

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    graphicsWebView = new QGraphicsWebView;
    graphicsWebView->setUrl(QUrl("http://www.google.com"));
    Deleter d;
    QTimer::singleShot(10000, &d, SLOT(deleteWebView()));
    return app.exec();
}

#include "main.moc"

After deleting graphicsWebView object there is still used about 2mb of
physical memory (more than 6 mb of virtual memory) by Webkit's OSAllocator
(I tracked mmap's calls by OSAllocator and then correlated with
/proc/pid/smaps). Much of the memory seems to be requested
by JSC::JIT::compile function.

Is there some way to completely clean QtWebkit after it was initialised?

This is Qt 4.8

Best regards
