memory leakage when running the examples

[mfkenson]

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.

pylibfreenect2/examples/multiframe_listener.py

Line 88 in 7fc73de

listener.release(frames)

This line is required to release memory for depth/color frames allocated by libfreenect2.

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).
