REVISION SUMMARY
  While investigating bug 407526, I discovered that most of the time is spent in SensorAgent::sendRequest. This is because it searches the whole queue lineraly, which could take a lot of time if there's a lot of requests. This patch speeds it up by using a `QSet` of outstanding requests, obviating the need to search the queues.
