You would want to stop another process from modifying the file while  
you're in the process of reading it.  On a CD, it wouldn't be an  
issue, but an NFS volume mounted read-only, or a file that's had  
"chmod 600" run on it during the load process, would be another matter.

But I think we can get a shared lock with read-only access, so that  
should be okay.
