bug#1620: Carbon: hang when edit file on network

[David Reitter]

This is a hang when doing file-buffer on a SMB volume (i.e. a local  
save, NOT with Tramp).  This seems to occur with another (Carbon?)  
Emacs as well, so I'm forwarding it on.

I don't have a SMB volume handy to try this out myself - the last time  
I used SMB volumes, I had no such problems.

bug#1628: Carbon: hang when edit file on network

[Paul Falstad]

Adding "unix extensions = no" to the server side smb.conf fixes the problem.

bug#1620: Carbon: hang when edit file on network

[Glenn Morris]

Thanks for the report. Emacs 22 is very old and has not been supported
for some time. The latest version is 23.3. Please open new reports for
any issues you have with the new version.
