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 Manager.
