First investigations with Qt 4.8 installed here shows that the majority of
runners (which run in threads) keep running until their timeout of 30 seconds
for a yet unknown reason. Since the number of threads executed in parallel is
limited, jobs block each other. This is noticeable especially on startup, where
more than a dozen of threads are started to load placemarks etc. This is done
in 1-2 seconds with Qt 4.7, while the threads blocking each other with Qt 4.8
extend this to several minutes. While the UI keeps responsive, all runner
related tasks take a very long time after startup to work. That are reverse
geocoding, searching, routing and parsing.
