Tramp talks to ssh server on save-buffers-kill-emacs

[Julian Scheid]

Hi,

I'm using Tramp 2.1.13 on Emacs 22.1 but I've seen this same problem 
with previous versions of both Tramp and Emacs.

My scenario is the following: while at work I am opening a couple of 
files using tramp. When I return home, I leave emacs running and still 
have the tramp buffers open. Still at home, without a connection to the 
server the files originally came from I try quitting Emacs and I get the 
following error message (in tramp's debug buffer):

  ssh: Error resolving hostname somehost: No address associated with 
nodename

and in *Messages*:
  File error: Process died

and Emacs refuses to quit.

If I want to quit Emacs without the connection I can use the following 
workaround: M-x kill-some-buffers RET y y y y y y y [...] - and once all 
tramp buffers are killed I can quit. But that's quite painful depending 
on how many buffers I have open, and usually I have lots.

My question is, why does Tramp try to talk to the original host when I 
do C-x C-c, but not when I do M-x kill-some-buffers? Is there a 
workaround so it doesn't attempt to talk to the host without a good reason?

Thanks,

Julian
