I have no idea why I did not use that to begin with, however. However, I think for git master we should allow Nepomuk::Service subclasses to set a priority like "BackgroundNonesense" or "UserInteraction" or things like that. Based on that we would set the priority. I suppose that the query service should get a higher prio (although I am not sure if that does change anything since most of the work is done by Virtuoso anyway.)
