Tried this, but couldn't quite get it working. Left the abortive attempt on branch jon/fiddling_with_data_sharing_strats

After conversation with @endurance, we can probably fix the underlying issue (frame queue filling up with more cams) by pulling the 'frame grabbing' responsibility off the main process ( i.e. #21 )
