Title:
  nexus 10 leaks resources during overlay operations

Status in Mir:
  Fix Committed
Status in “mir” package in Ubuntu:
  Triaged

Bug description:
  If you run the server with overlays enabled, after a while you'll see:

  W/hwcomposer(22768): fence dup failed: Too many open files
  E/hwcomposer(22768): ioctl S3CFB_WIN_CONFIG failed: Too many open files
  F/hwcomposer(22768): ioctl S3CFB_WIN_CONFIG failed to clear screen: Too many open files

  which probably means we're leaking fences around the hwc set when
  overlays are enabled. This doesn't seem to effect the other classes of
  devices. It shouldn't affect the unity stack, as the overlay
  optimization is currently disabled.
