Hammer 2 and xlinks

I have a huge backlog of things to post, so this is originating from the 17th: Matthew Dillon has been working for some time on hardlinks and Hammer 2.  Hardlinks are the same file, presented in multiple places.  This can be a problem when your filesystem keeps infinite, writable snapshots.  The solution he just commited is called ‘xlink’ and the commit message has details.
