Inferior Octave delay

[Sean O'Rourke]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

With a recent CVS Emacs, inferior Octave will cause Emacs to hang
until the command executed produces at least some output.  To show
this effect, start up an inferior octave and type "sleep(1);disp(1);".
Until about a week ago, this would immediately return control to
Emacs, wait a second, and display a "1".  Now it hangs Emacs until the
sleep is done.  However, if you reverse the "disp" and "sleep", it
immediately displays the "1", and does not hang Emacs during the
sleep.
