If you require your data cache to be guaranteed to be consistent you
still have to use some form of locking to ensure that nobody tries to
read a file that is in the process of being updated on the server.
If so, close-to-open helps by ensuring that you can safely rely on
more lightweight locking protocols such as that provided by the
"lockfile" utility (a.k.a. dotlocking) instead of the full NFS Lock
