memory leakage when running the examples #43

Both examples multiframe_listener.py and selective_streams.py make my mac running out of memory after keep running 1-2 minutes. I have 16GB memory. It took only few seconds to increase 500MB memory usage. The libfreenect2's example "Protonect" has no problem. The memory usage is only about 110MB.

Did you run both examples with no modifications? If so, could you please debug which line causes memory leak? I don't have Kinect v2 right now so I cannot debug examples, sorry. It might be worth trying different packet pipelines (OpenGLPacketPipeline, CpuPacketPipeline, etc).
