--text follows this line--
This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':


---
When I run a Python 3.3.4 prompt inside Emacs 24.3 on Windows 7, correct
commands are evaluated immediately, but incorrect ones are delayed (I have
to press Enter one more time), as seen below:

    >>> 1
    1
    >>> nonsense
    >>>
    Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    NameError: name 'nonsense' is not defined
---

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

I was able to replicate this on a Windows 7 machine running Python
3.3.4.  Adding the "-u" switch to `python-shell-interpreter-args' seems
to help as no occurrences of the issue happened ever since.

Added a commentary about this at revno 117392 in the emacs-24 branch
just in case this issue gets to mess with more people.


Cheers,
Fabián
