No kidding... I knew about the simulated byte-range locks using full file
locks bit, but I don't remember knowing that giving users 'k' will
accomplish the same thing. Do we really need to be at 1.4.5 to get the
new locking semantics? I thought the locking support change happened

Apparently not. I was thinking that we needed to upgrade the fileservers
in order to begin taking advantage of the simulated file locking feature
Thank you for the clarification.
