That's a pretty strange design though. Once a client has closed a
file it really should ensure an update on the server (IMHO).

The idea of keeping oplocks across file open/closes just "in
case" the file will be opened again is rather risky (IMHO).
This is one of the things I don't like about Windows oplocks.
