Be that as it may, this configuration can work. It worked for us.
There may have been working copy problems once in awhile, I'm not
sure, as I wasn't one of the developers using this configuration. But
I was one of the admins in charge of the Subversion server, and I
don't recall hearing complaints about this from the developers who
were using it.

If the working copy gets hosed, check out a new one. If it happens
too often, try a different version of Samba, or try NFS maybe? Not sure.

It's contrary to the notion of committing things once they've been
tested, which I subscribe to. Whether this matters for the OP is of
course for him to decide. But in the web site development shop where
I worked, it's common for a programmer to make a small change in the
text file, save, press reload in the browser, go back to the text
editor, make another small change, save, reload in the browser, back
and forth very very quickly until they get whatever it is they're
working on right. To force them to commit after every little save
(and invent a commit description for every new attempt) would slow
them down immensely. Maybe this applies in the OP's case too.
