What application am I talking about here, for example? http://oss.sgi.com/pipermail/xfs/2013-June/027159.html Basically, Swift is trying to emulate Direct IO because python does't support Direct IO. Hence Swift is hacking around that problem and causing secondary issues that would never have occurred if Direct IO was used in the first place.
