The new Samba 2.2 locking API is provided via a separate library, that
will allow for other server-type applications to, in effect "share"
locks, or at least honor each other's locks. Unfortunately, because of
what a Windows client EXPECTS when it opens a file on a server as
opposed to what a Mac EXPECTS when it opens a file on a server, this may
not prevent ANYTHING bad from happening. Macs are very sensitive to
"permission" changes after a file is opened - If when the file was
opened the Mac was given write permission, it expects the ability to
write to the file at any time until IT closes the file - This is a bad
assumption (just one of many), and will most probably collide with ANY
collaborative locking mechanism/API.
