IIRC, the image data is ref-counted internally in the driver (per
Khronos extension docs). So you not only need to remember to destroy the
image, but also need to delete all associated GL textures. Only when all
such references are gone will the buffer be freed.

Bug description:
  Nexus 4 running latest stable image -

  current build number: 25
  device name: mako
  channel: ubuntu-touch/stable/ubuntu
  last update: 2015-12-08 11:53:16
  version version: 25
  version ubuntu: 20151118.2
  version tag: OTA-8
  version device: 20150911
  version custom: 20151118.2

  I'm running the following command to capture a screenshot of a running
  app, the unity shell, the splash screen when apps load etc.

    adb shell mirscreencast -m /var/run/mir_socket  -n1

  I'm doing this in a script, across many hundreds of apps, so I'm doing
  it a lot. I'm seeing my script get wedged fairly often with errors
  such as this one:-

  [1449575031.562843] <ERROR> MirConnectionAPI: Caught exception at client library boundary (in release): /build/mir-AHj2eT/mir-0.17.1+15.04.20151105.1/src/client/rpc/stream_socket_transport.cpp(168): Throw in function virtual void mir::client::rpc::StreamSocketTransport::send_message(const std::vector<unsigned char>&, const std::vector<mir::Fd>&)
