No such thing with Samba, as the second user might waist hours on editing an already open file just ending with no results!! Don't you think this is stupid?

Samba behaves identically to Windows 2000 in this regard
(keeping deny modes on shares). If your application behaves
one way with a W2K server it should behave exactly the
same with Samba. Indeed this is part of our test process.

MS Word does indeed isue this warning against Samba 3.0.

I'm not sure of the problem you're experiencing but please
be aware Samba is coded to give the same response as Windows.
