World readable access to segmented object produces 401, even if _segments is also world readable.
|||OpenStack Object Storage (swift)||
So, seems I've stumbled across something that used to work in Essex, but is no longer working in Folsom. Using the swift tool, upload a segmented object to a container with a `.r:*` read ACL. Accessing the object anonymously produces a 401 as expected, as the segments are in the companion _segments container. After giving `.r:*` access to the _segments container, anonymous access to the segmented object used to work. In Folsom, it continues to produce a 401.
