Dear all,
when I C-c C-c in:
#+BEGIN_SRC sh
gnome-terminal
#+END_SRC
a gnome-terminal window appears, but Emacs hangs until I close it.
In the *Messages* I get:
executing Sh code block...
Wrote /tmp/babel-2307H-J/ob-input-2307i3c
(....here Emacs hangs... then I close gnome-terminal)
Error reading results: (beginning-of-buffer)
Code block produced no output.
If I use emacs -Q ( evaluating just (org-babel-do-load-languages
'org-babel-load-languages '((sh . t))) ) this doesn't happen.
Do you have any idea of what could be triggering such behavior?
Thanks,
Giacomo

My guess is that Emacs is waiting for the final output from
`gnome-terminal`, which doesn't get sent until you close
`gnome-terminal`.

What exactly were you expecting? If you open a terminal window and
start, say, firefox from it, the terminal window will "hang" until you
close firefox - then you get another prompt and can give it some more
input. This is no different. It would be nice if emacs were
multithreaded, but it isn't (at least not yet).

When you say "this" doesn't happen, what do you meant by "this"? How
does this example compare with the previous example? They look
completely different to me.

One additional note - you can start the gnome-terminal process in the
background:
#+BEGIN_SRC sh
gnome-terminal &
#+END_SRC
The shell will not wait for the process to finish and emacs will not
hang.
