Git commit 462a06ea08d2ece143fe0daa59ceb8523ed0b763 by Dawit Alemayehu. Committed on 17/01/2012 at 21:12. Pushed by adawit into branch 'KDE/4.8'. Avoid using a nested event loops for synchronous XMLHttpRequest by letting Qt's networking code, which can block without a need for a local event loop, deal with such requests.

Committed on 11/05/2012 at 19:35. Pushed by adawit into branch 'KDE/4.8'. Revert commit 462a06ea as it causes many regressions. Use KIO::synchronousRun to fulfill synchrounous XmlHttpRequest instead. Unofrtunately this means that the fix for the crash reported in bug# 287778 is reverted until we can find a solution for the side effects of using nested event loops.
