There's a very serious known issue with the image cache cleanup code when you're using shared storage:

The fix is invasive and risky, but there's a known workaround (i.e. disable the image cache manager) which Vish has documented in the release notes.
We may just disable the image cache manager by default for the release.
Is it sufficient to just set remove_unused_base_images to False by default?
From IRC:
<vishy> yeah although I think setting the interval=0 might be better <vishy> since it will be going crazy md5summing on shared storage and still running all the logic otherwise <vishy> so it may not delete images but I suspect the performance will still be horrible
Cheers, Mark.
