bug#2920: emacs freezes because of lock files in samba server

[Sergio Roa]

Just to add some information, which I sent already to 
emacs-pretest-bug@gnu.org, because I didn't know how this bug system 
works...

I found that the source of the problem is the lock file for Samba 
directories:

A link in the client "aliena.dfki"

.#prueba.xml -> sergio@pandion.dfki.uni-sb.de.10144

is created and not deleted (in the server "pandion.dfki") after emacs 
quit. Therefore after the second and subsequent editions of the file 
emacs freezes.

I found that in fact when I perform the command

rm .#prueba.xml

on the mounted directory in the client computer, the operating system 
tries to delete the file but it doesn't manage to delete it in the 
server... This behaviour only occurs with links to other files. For 
instance, I created a file "otraprueba.xml" which points to "prueba.xml" 
and then tried to delete it (working on the client computer), without 
success.

So, apparently it is a Mac OS or Samba problem.

Just for information: the workaround is to set the following in 
/etc/samba/smb.conf (in my case is an Ubuntu linux samba server):

unix extensions = no

so that now there is no problem editing the files mounted in a Volume in 
my MacOS Leopard client :)
