Hi, I'm finding that plot windows freeze running octave in inferior-octave mode

GNU Emacs 24.3.1
GNU Octave, version 3.8.1

Start Emacs
$ emacs -Q

Start an Inferior Octave Process
M-x run-octave

Octave Commands to produce plot
x=1:10
plot(x)

Plot window is frozen. The same commands entered directly into octave
in a terminal or octave started in emacs shell mode work fine.

Thanks, John.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

Thanks for the report.
By experiment, this is already fixed for the next release of Emacs.
Try it out at
http://alpha.gnu.org/gnu/emacs/pretest/emacs-24.3.93.tar.xz 

(Plain M-x run-octave hangs for me in 24.3.)
