I ran `valgrind --leak-check=full ./build_isolated/intra_process_demo/image_pipeline_with_two_image_view`.  Looking at the output from that, it looks like the leaks are coming from somewhere down in the OpenCV code.

The leaked memory from within `cvCreateMat` is constant - two times (one per window) independent how long the process is running. So this is not responsible for the increasing memory reported.
