Thanks Darryl.  However, I don't think this solution will work in our 
usage.  We're running a blog.  Administrators get un-cached access, 
straight through varnish.  Then, when they publish, we issue a purge 
across the entire site.  We need to do this as there's various bits of 
navigation that'd need to be updated.  I can't see that we can do this 
if we set obj.ttl.

Has anyone any recommendations as to how best to deal with purges like this?
