Ok, I just mailed Andreas privately, but wanted to let everyone
who might be suffering from the same problem know the status.

I have now re-written the Samba open code to provide
the "deferred" opens that Excel seems to require. I have a
(large) patch against the current Samba subversion 3.0 code
that should fix this problem.
                                                                                                                        
I've been testing it here and it passes all my automated tests,
plus it is valgrind (memory leak and overwrite) safe.
                                                                                                                        
If you can cope with applying a diff patch to svn checked
out code (if you don't know what that means don't ask for
the patch :-) please let me know and I'll mail it out.

Don't put it into production but for people who have users
who can reproduce it at will I'd be very interested to see
if this fixes the problem.
