Looking at log of managers.py and connection.py I don't see any significant
changes landed after 2.7.6 was released (Nov, 10). So it looks like those
bugs should be fixed in 2.7.

As I said on the meeting I plan to provide change request to Neutron with
some integration with this patch.
I'm also going to engage people involved in rootwrap about my change


Kind regards, Yuriy.
