Unfortunately it does not work for me with python-2.7, only with python-3.3,
tested on Fedora 18 x86_64:

$ python3 -m threading;echo $?
0
$ python3 -m threadin;echo $?
/usr/bin/python3: No module named threadin
1

but:

$ python2 -m threading;echo $?
Traceback (most recent call last):

python3-3.3.0-0.3.b2.fc18.x86_64
python-2.7.3-13.fc18.x86_64

GDB moveover currently is not compatible with python3.x at all.

I do not know much Python but I would guess thread-less Pythons are rare,
aren't they?  There would be also a possibility to assume Python is threaded,
if one already links with Python.


Otherwise I am fine with the patch.


Thanks,
