There is no specific requirement that one be done before the other.  We
haven't changed the data formats or protocol exchanges up to this point.

File locking is simulated in the client.  The client obtains a full file
lock from the file server and then doles out byte range locks locally to
the application.

The change in the file server from 1.2.13 to 1.4.5 will provide you with
large file support and a modification to the locking semantics so that
users that have 'w' permission do not need to explicitly have 'k'
permission.  Of course, if you have already granted 'k' permission to
your users there will be nothing gained.

Is there something else you were thinking of?
