[OpenAFS] pre-fetch cache

[Matthew Cocker]

We run our whole dual boot XP/Debian lab system with any application
that can run from afs in afs. Even big apps work well especially now
windows has a persistent cache.

The big benefit (aside from smaller images and easier updates) has been
we set our network up to handle samba/NFS loads but since we have
moved to AFS it is just idling along.

This means that we now have bags of network capacity to use for really 
important things like our sending live video stream of our office fish 
tank to all the lab print stations to be used as the screen backdrop.

Cheers

Matt
