[OpenAFS] pre-fetch cache

[Ken Aaker]

Hi Jim,

I browsed through the paper and it looks close to what I was thinking 
about, so I'd suspect that the general conclusions probably still hold true.

If there were iAFS servers introduced, I think they would be "delay 
servers". What I was thinking was a little different, and might be 
something that I read about in one of the IBM "Storage Tank" 
descriptions. I was thinking that the file server would use a callback 
to the clients to say that "the chunk that you want is at this address 
(of a closeby client cache) with this ID". The chunk could be 
transferred and the chunk registered with the fileserver when the 
transfer is done???
