Loader::scheduleServePendingRequests seems to be called all the time, the
backtrace is the same for all:


 qtwebkit4.dll!WebCore::Loader::servePendingRequests(WebCore::Loader::Priority
minimumPriority = 0) Line: 166, Byte Offsets: 0x10   C++
    qtwebkit4.dll!WebCore::Timer<WebCore::Loader>::fired(void) Line: 98,
Byte Offsets: 0x14 C++
    qtwebkit4.dll!WebCore::ThreadTimers::sharedTimerFiredInternal(void)
Line: 115, Byte Offsets: 0x114  C++
    qtwebkit4.dll!WebCore::SharedTimerQt::timerEvent(QTimerEvent* ev =
0x00000000) Line: 106, Byte Offsets: 0x3c  C++
    qtcore4.dll!QObject::event(QEvent* e = 0x00000000) Line: 1276, Byte
Offsets: 0x33c  C++
