as AFS does not cache files but chunks, the above solution would just
keep the first chunk in the cache, not the complete file.
Also, Ted did not say that files were only used for read. If yes,
the need for a RAM cache is relative: on modern systems, if files are
read frequently then they will reside in the system's buffer cache anyway.
I agree though that being able to pin chunks in the cache could have
its merits, for example on a notebook if you know that the next time
you connect it'll be over a slow line. Can't be that big a change...
