pypy testing

Some results of pypy (+JIT) testing.

statfs with pypy-c (PyPy 1.6.0-dev1 with GCC 4.5.2)

# time ls -l /srv/statfs/ >/dev/null
real    0m1.236s
user    0m0.000s
sys     0m0.020s

statfs with Python (Python 2.7.1+)

# time ls -l /srv/statfs/ >/dev/null 
real    0m0.742s
user    0m0.000s
sys     0m0.020s

It seems that here PyPy runs slower than plain Python… We need to test if there is a reason to run the code under PyPy at all.

remove Queue.Queue from iproute2

One should use something more reasonable than Queue.Queue. Really. It is tooooo slow.

support IPv6-enabled systems

having ipv6-addresses enabled causes e.g. get_route to break:

In [4]: iproute2.get_route("8.8.8.8")
---------------------------------------------------------------------------
