Huh, that's interesting and surprising, thanks for the link. Is this method of stashing compressed data in the xattrs something that's currently commonly used by OSX? Or is it just some weird infrequently used trick? I see this on the linked page:
> Compression is most often used for files installed as part of Mac OS X; user files are typically not compressed (but certainly can be!)
Are a lot of system files compressed like this? Is there any way a user file might be compressed in such a way through normal user actions?
