To prevent other smbd's from granting oplocks on the base
file. They need to have a share mode entry to achieve that.
There might also be some interaction needed with delete on
close. My guess is that with your patch one or more of the
other tests will fail (but I haven't checked :-).

I think Volker's fix is the correct one, but I'll have to
spend some time going through it carefully tomorrow before
pushing it :-).
