i am not reccomending 'cache bypass' for everyone.  if we ever get the mods
i certainly wouldnt ask for it to be placed into openafs.  its just
something we thought about doing.  getting >1G files from afs is very very
slow through the cache manager.  possibly something like 'afs ftp'
might be an easier solution though.  i.e. a direct read from the fileserver
at the userspace level.
