[FEATURE] Exeperimental launch on python3.4

[Ignat99]

List of some trouble on address-model=32 and fix for it:

pip install cython git+git://github.com/surfly/gevent.git#egg=gevent
sudo pip3.4 install cython git+git://github.com/abourget/gevent-socketio.git#egg=gevent-socketio

But import of modules not correct on Python 3.4

./counterblockd.py --help

Need in file (gevent/gevent._semaphore.c:3142) that generate by cython change -1 to 0 in line 3142. Because the modules are imported incorrectly in Python 3.4

=============================== For package Python 3.4 need extra settings
ln -s /usr/lib/libpython3.4m.so.1.0 /usr/lib/libpython3.4
include <python3.4/config.h>

In setup.py

python-greenlet/greenlet#62

 httpparser = Extension('geventhttpclient._parser',
                sources = ['ext/_parser.c', 'ext/http_parser.c'],
                libraries = ['boost_python-py3.4'],
                libraries_dirs = ['/usr/local/lib'],
                include_dirs = ['ext'])

But most of problem inside:

• gevent
• geventhttpclient
• gevent-socketio
• gevent-websocket
• greenlet

In my opinion, these packages are not safe under python 3.4.
Many tests do not pass, within the code is very confused.

closing this, best to have it in a separate branch
