Call in the SWAT team to shoot emacs but spare Firefox

Call in the SWAT team to shoot emacs but spare Firefox

[jidanni]

I can't take it any longer.
I start Firefox by one of the million ways one can there in emacs.
Then hours later I wish to quit emacs, but...
   Active processes exist; kill them and exit anyway? (yes or no)
That's right. Emacs demands taking Firefox along with it to the grave,
It's either that, or it refuses to quit.
What do I have to do? Call in the SWAT team to shoot emacs but spare
its hostage Firefox? Yeah well I bet emacs has wrapped a bomb around
them both so there will be no survivors ("Shoot me and I'll take out the
whole process tree, motherf***er!")
So does one need to write a batch(1) job wrapper script to start Firefox
away from the hands of terrorism? Why can't there be a third answer to
   Active processes exist; kill them and exit anyway? (yes or no)
i.e., "No. Don't kill them, but exit anyway."
What kind of cheap 2nd hand Woolworth's software can't do that these days?

And P.S., there might be more than one active process, so be sure to
allow the user to pick and choose and don't just give an all or nothing
solution... when fixing this in the emacs trunk.

And don't just say
> start Firefox from another windo outside emacs
as that is avoiding the issue.
> No reason to exit emacs till the end of the work day anyway
What if emacs gets "messed up" and one wants to restart it without
disturbing other processes?

Heck, must have missed the Free Software stand in my local Woolworths.

Would be helpful to know what OS this is for.

In any case, there is a page on the emacswiki that handles exactly
this - Persistent Processes:

$ emacs --version
GNU Emacs 24.0.50.1
$ BROWSER=firefox emacs -Q -nw
M-x browse-url example.com
C-x C-c
Active processes exist; kill them and exit anyway? (yes or no)

Try it.

set-process-query-on-exit-flag

The return value of browse-url-default-browser and the various browse-
url-default-*-browser functions isn't documented, but they look like they
return the asynchronous process, so perhaps they could be advised to call
(set-process-query-on-exit-flag ad-return-value nil).

Try "nohup firefox" in the above, as myself and others on this thread
have suggested. 

Also, it would help to know your OS - the above won't work under
windows, for instance.
